A senior MP today said a suspected attempt to kill a Russian ex-spy bears ‘all the hallmarks’ of a Kremlin attack.
Tom Tugendhat said if proven the possible poisoning of Sergei Skripal, 66, would be a new escalation in a ‘soft war’ by Russia against the UK.
The chairman of the Commons Foreign Affairs Committee said new sanctions should be imposed against Russia if it was proven the Kremlin ordered the attack.
Mr Tugendhat will demand answers from ministers in the Commons at around 12.30pm today after Commons Speaker John Bercow agreed to an emergency debate.
The warning comes after shadow defence secretary Diane Abbott warned ministers not to allow ‘London and the Home Counties to become a kind of killing field for the Russian state’.
British relations with Russia have been chilly since President Vladimir Putin was suspected of personally ordering the attack on Litvinenko.
Defence Secretary Gavin Williamson yesterday repeated warnings of the military threat from Russia, warning Putin had ‘hostile intent’ toward Britain.

Sergei Skripal is fighting for his life after being exposed to an unknown substance. He is a former colonel of Russia’s military intelligence, was convicted in Russia in 2006 on charges of espionage for Britain’s MI6 intelligence agency
Skripal who had recently told police he feared for his life, was rushed to hospital after collapsing on a bench outside a shopping centre in Salisbury on Sunday.
He was found with a 33-year-old woman, who is also fighting for her life. She is thought to be a family member.
Health chiefs said the pair had been exposed to an ‘unknown substance’.
Mr Tugendhat said that if Russian involvement was proved, the Skripal case would amount to a further salvo in a ‘soft war against the UK’ conducted by Mr Putin’s administration.
‘It is too early to say whether it is certain or not, but it certainly bears all the hallmarks of a Russian attack,’ Mr Tugendhat said.
‘If it is, then I am calling for a whole-of-Government response. Too much of this has been left to the Foreign Office or the Home Office separately.
‘What needs to be done is for the whole Government to get involved in responding to what amounts to a soft war against the UK, taking in the cyber-hacking they have done and the various aggressions they have been involved in.’
Mr Tugendhat said that the eventual response to any Russian involvement in the Skripal case could include travel bans, sanctions and the imposition of Magnitsky Sanctions legislation allowing the assets of human rights violators to be frozen in the UK.

Diane Abbott (file image) today demanded answers from ministers about an apparent attack on a Russian spy she said had ‘striking similarities’ to the murder of Alexander Litvinenko
Ms Abbott told the BBC Radio 4 Today programme: ‘It’s important not to speculate without knowing everything it but it does bear a striking similarity to the death of Litvinenko who was poisoned by the Russian state and before that Markov who was killed bizarrely by somebody stabbing him with an umbrella with poison on the tip.
‘That was put to the Russian state and the problem with these things is sometimes truth is stranger than fiction.’
Ms Abbott highlighted a BuzzFeed investigation that named as many as 14 people who died in suspicious circumstances linked to Russia.
She said the cases did not need to be reopened but that the Home Secretary should reassure the public all of them were probed properly after they were exposed over the past two years.
Ms Abbott added: ‘I will be writing to Amber Rudd to say if it does prove to be the case the Russian state is involved in thus latest death what assurances can she give about the rigour of the investigation and where we go from here.
‘I don’t like defaulting to a red menace analysis but we can’t allow London and the Home Counties to become a kind of killing field for the Russian state.’

Ms Abbott’s intervention came as the Government remained tight lipped about the circumstances surrounding Skripal.
Julian Lewis, the chairman of the Commons defence committee, told MailOnline: ‘If a second Russian former spy has been targeted in the UK, after the reckless use of polonium to kill Mr Litvinenko, it shows that the Kremlin has not the slightest interest in a positive relationship with the West and has learned nothing from the outrage caused by its previous public act of murder.’
Labour MP Chris Bryant, who chairs the All-Party Parliamentary Group on Russia, called for a Government minister to come to the despatch box today to update the Commons on what is known about the Skripal case.
Mr Bryant said: ‘We have got to be a little careful about establishing the facts – and I very much hope a Government minister will come to the chamber later today to explain what we do know – but we know Putin’s record of using excessive violence.
‘There is a long list of Putin opponents who have been bumped off around the world. The fact that this happens just before presidential elections, I would suspect, is not circumstantial.
‘We can’t be having Russian operatives bumping people off in the UK. I was very critical of both David Cameron and Theresa May in the 2010 Parliament because they kept refusing to allow a full investigation of the Litvinenko murder. It was years before Theresa May finally allowed one to happen.
‘If something similar has occurred in this situation, then we shouldn’t let the grass grow under our feet.’
Skripal, who lives in a £350,000 house in Salisbury, is thought to have suffered a double family tragedy after his son was killed in a car crash in Russia last year – five years after his wife suffered the same fate and was buried in Britain.
As police experts desperately attempt to find out what substance Mr Skripal was exposed to, authorities have urged anyone who feels ill to contact 111 .
Last night, police shut down a branch of the Italian restaurant chain Zizzi in the cathedral city ‘as a precaution’ in connection with the incident, suggesting one or both of them may have dined there before.
They also closed Salisbury Hospital’s A&E unit to protect other patients and sealed off part of the city centre.
Mr Skripal was previously known for allegedly receiving £78,000 in exchange for taking huge risks to pass classified information to MI6.
Defence Secretary Mr Williamson yesterday called for the UK to wake up to the threat posed by Russia.
He warned that the Kremlin had developed a much more aggressive posture towards the UK in the past 12 months and the country should not sit submissively by.
With relations between Britain and Russia believed to be at an all-time low, Mr Williamson told MPs that the country needed to ‘match what Putin is doing with Russian forces’.
During defence questions in the Commons, he said: ‘Putin has made it quite clear that he has hostile intent towards this country.
‘We’ve been seeing the build-up of his forces across the Eastern Front and in terms of what they’re doing over many years now – we have to wake up to that threat and we have to respond to it.
‘And it is not just through nuclear weapons – our continuous at-sea nuclear deterrent is absolutely integral to maintaining the peace, but it is also through conventional armed forces. We have to match what Putin is doing with Russian forces.’
His comments came after he was asked by Labour’s Barry Sheerman about comments the Russian president had made in a state-of-the-nation speech last week.
Mr Sheerman pointed out that Mr Putin had basically announced ‘a new Cold War’.
Mr Putin boasted in his speech that Russia had developed an arsenal of invincible nuclear weapons that are immune to enemy detection.
On Sunday, emergency services had said they suspected fentanyl, a synthetic opiate up to 100 times more potent than heroin, may have been involved, the Salisbury Journal reports.
A spokesman for Public Health England (PHE) said anyone exposed to the unknown substance had been decontaminated ‘as is standard practice in situations like this’.
He added: ‘Scientists from PHE’s Centre for Radiation, Chemical and Environmental Hazards, will continue to assist the response and review information as it becomes available.’

Yesterday, Constable Holden said: ‘Yesterday afternoon, at approximately 4.15pm, Wiltshire Police received a call from a member of the public who was concerned for the welfare of two people.
‘The two people – a man aged in his 60s and a woman aged in her 30s – were found unconscious on a bench in The Maltings in Salisbury.
‘Police officers, as well as colleagues from the ambulance and fire services, attended the scene and cordons were put in place.
‘The pair, who we believe are known to each other, did not have any visible injuries and were taken to Salisbury District Hospital.
‘They are currently being treated for suspected exposure to an unknown substance. Both are currently in a critical condition in intensive care.
‘Because we are still at the very early stages of the investigation, we are unable to ascertain whether or not a crime has taken place.
‘A major incident has been declared today and a multi-agency response has been co-ordinated.
‘Alongside our partner agencies, we are conducting some extensive inquiries to determine exactly what led to these two people falling unconscious and clarify whether or not any criminal activity has happened.
