White Widow Sally Jones tried to recruit a Pizza Express chef to assassinate the Queen at Britain’s 70th anniversary VJ Day celebrations.
Jones, from Chatham, Kent, travelled to Syria to join ISIS with her 12-year-old son Jojo but died following a US airstrike in June.
It is believed her son was also killed in the attack, possibly due to Jones using him as a human shield.
And it has now emerged she groomed a former chef in a bid to persuade him to carry out a Boston marathon-style bomb at an event attended by the Queen.

The man, known as Adam, posed as a 19-year-old woman called Izdihar to expose IS fanatic Jones, said she gave him ‘bomb-making kits’.
He told The Sun: ‘She was desperate for me to carry out an attack on the VJ Day celebrations where the Queen would attend.
‘She sent me bomb-making kits and told me she would put me in touch with jihadi sisters in Britain.
‘But she also used a lot of emojis and smiles to put me at ease and come across nice while planning with me to kill.’
She told the former chef that he was going to make a ‘pressure cooker’ bomb which was the ‘same’ as the one the Boston bomber made.
The former glamour model asked Adam to give her the receipts for the materials he bought for the bomb.

He added: ‘It was pretty scary at times. Once we realised what she was planning we handed all the material over to the authorities.’
The Queen led the ceremonies to mark the 70th anniversary of VJ Day in August 2015.
Hundreds of war veterans had gathered in London for the historic occasion to remember the millions killed during the Second World War.
Around 350 veterans and their families and carers later met with royals and the Prime Minister at a garden party hosted by the Royal British Legion in the grounds of Westminster Abbey.
In 2013, two bombs detonated at the finish line of the Boston Marathon, killing three people and injuring hundreds of runners and spectators.
