Boris Johnson’s girlfriend Carrie Symonds is seen for first time in two months

Carrie Symonds has been pictured in public for the first time in more than two months.

The partner of Prime Minister Boris Johnson was spotted arriving at the more-discreet back entrance to No 10 Downing Street in central London yesterday.

It is the first time she has been pictured in public since she was seen triumphantly entering No 10 alongside Mr Johnson after his election win on December 13.

In recent weeks, she is said to have been spending more time away from Downing Street, instead opting for Chequers, the remote Buckinghamshire country house of Prime Minister.

Despite remaining active on social media, Miss Symonds failed to document her and Mr Johnson’s much-publicised New Year holiday trip to the Caribbean.

The couple flew out to Mustique on Boxing Day last year and stayed for ten days at their hideaway, which boasts four-poster beds, open terraces and an infinity pool. 

The Caribbean island is extremely popular with VIPs and celebrities thanks to its notoriously private reputation.

For their post-Christmas break, Mr Johnson and Miss Symonds flew British Airways to St Lucia and then used a small propeller plane for the hop to Mustique.

According to the villa’s advertised price of $27,000 per week at that time of year, a ten-day stay would normally have cost $38,500 (£29,500).

The villa is priced at varying rates depending on the time of year. But in the two weeks leading up to January 4 it was advertised at the premium rate.

Mr Johnson and his girlfriend spent most of their time in seclusion at their bolt-hole, eschewing the chance to join in the wild New Year’s beach party that was attended by Rolling Stones frontman Sir Mick Jagger, Bond star Daniel Craig and model Kate Moss.

But on New Year’s Day, the Prime Minister and Miss Symonds dropped in to the Caribbean’s most famous hostelry, Basil’s Bar.

The mystery over who funded the trip deepened last night after the luxury villa’s owner told the Daily Mail it was not a freebie.

Sarah Richardson, who owns the home where the two stayed, confirmed that she and her husband Craig had rented it out – and that they had ‘got paid’.

But she said she had ‘no idea’ who had actually covered the cost of the rental as it had been handled by The Mustique Company, the island’s management company.

It comes after David Ross – the British businessman whom Mr Johnson declared had provided the £15,000 ‘benefit in kind’ – denied he had been the one to pay.

The Prime Minister triggered the mystery by naming Mr Ross as the ‘donor’ of the holiday in the Commons register of interests on Wednesday.

But although the former Carphone Warehouse tycoon accepted that he arranged the trip, his spokesman insisted that he did not ‘pay any monies whatsoever’. 

It means that the identity of the person who covered the cost of the trip remains a mystery.
