Sasha Swire also alleges that Mr Cameron’s wife Samantha was only able to join him for his resignation speech after a large negroni cocktail.
She makes the claims in her forthcoming bombshell book about her life as the wife of former Foreign Office minister Sir Hugo Swire.
Fortified: Samantha Cameron with husband David as he resigns
In the latest extracts Lady Swire, 57, recalls visiting Mr and Mrs Cameron at their Oxfordshire home the weekend after the EU referendum in June 2016.
She says her husband had texted Mr Cameron to say ‘we are around if he wants cheering up’ and he texted back asking them to come ‘with two fat Cohibas and plenty of booze’. Cohiba is a premium brand of Cuban cigar.
Lady Swire says Mrs Cameron told her she did not think she could join her husband for his resignation speech – made in Downing Street at about 8am, hours after the result was announced – ‘without drinking a large negroni’.
She adds: ‘When they walked back inside, Dave apparently recoiled from her gin-sodden breath.’
It was ‘almost wholly’ directed against his Cabinet colleague Michael Gove, who had jointly led the Vote Leave campaign with Boris Johnson (pictured with David Cameron)
When the Swires arrived at the Camerons’ Oxfordshire home, Mr Cameron was not there but his wife was and she was ‘devastated – not by Dave’s departure, but by the “stupid” decision the country has made’, Lady Swire claims.
‘When Dave arrives, he makes a lethal negroni before we progress to endless bottles of wine, whisky and brandy,’ she writes in the book, the latest extracts of which were published in The Times yesterday.
Mr Cameron, who resigned as prime minister and leader of the Conservative Party after Britain voted to leave the EU in the referendum, was ‘incandescent with anger’. It was ‘almost wholly’ directed against his Cabinet colleague Michael Gove, who had jointly led the Vote Leave campaign with Boris Johnson.
‘As for Boris, he says that this whole episode was to do with his leadership ambitions and that he despised his lack of ideology, which is a tad ironic,’ Lady Swire says.
Revelations: Lady Swire with Sir Hugo
‘David tells us that even when he switched sides, Boris was telling him via texts that Brexit “would be crushed like the toad beneath the harrow” and that he (David) would survive.’
Lady Swire adds how after dinner Mrs Cameron ‘conks out on the sofa’ while Mr Cameron and her husband, whom she refers to as H, ‘are now chomping on cigars’.
In an entry the following year, Lady Swire says Mr Cameron is by then billed as ‘one of the most prominent global influencers of the early 21st century’ by the Washington Speakers Bureau. But she says ‘below the bravado’ she feels there is a ‘residue of sadness’.
Lady Swire’s book, Diary of an MP’s Wife: Inside and Outside Power, is due out on Thursday next week. A spokesman for Mr Cameron said yesterday: ‘We are not commenting on the book.’
… and Boris ‘knocks back cheapo plonk’
Lady Swire recalls how Boris Johnson drank cheap wine ‘at an alarming rate’ during a dinner at No 10 Downing Street.
It happened in August last year when her husband Sir Hugo Swire told the Prime Minister that he was retiring as an MP at the 2019 general election.
Lady Swire tells how she watched Mr Johnson as he ‘stuffs in more mouthfuls and knocks back the cheapo plonk at an alarming rate’.
She describes how she looked at his ‘pale, sweaty face’ and he looked back ‘as if he is working out if I’m shaggable’, adding: ‘He’d probably do the same if a sheep walked in the room.’ She describes Mr Johnson as ‘cheeky’, ‘flippant’, ‘enthusiastic’ and ‘bombastic’.
Lady Swire says that Mr Johnson’s fiancee Carrie Symonds, whom she refers to as his ‘hot young vixen’, was not at the dinner because she had ‘p***** off to Greece, apparently’. This ‘disappointed’ Lady Swire’s husband, ‘who thought he might get to sit next to her’.
Lady Swire adds: ‘For all his hinterland and hot young vixen and his agile mind, Boris just came across as someone who is desperately lonely and unhappy.’
