Boris Johnson has been accused of squeezing the thighs of two different women sitting round the same table at a boozy private lunch.
Writing in the Sunday Times, Journalist Charlotte Edwardes said the Prime Minister put his hand “high” up her leg.
And she said he had “enough inner flesh beneath his fingers” to make her “sit suddenly upright.”
Ms Edwardes said she later recounted the tale to another guest at the same lunch, who said: “Oh God, he did exactly the same to me.”
The alleged incident took place at the offices of the Spectator magazine just after he took over as editor in 1999.
Ms Edwardes wrote: “I’m seated on Johnson’s right; on his left is a young woman I know.
“More wine is poured; more wine is drunk. Under the table I feel Johnson’s hand on my thigh. He gives it a squeeze. His hand is high up my leg and he has enough inner flesh beneath his fingers to make me sit suddenly upright.”
She also said he referred to Marina Wheeler as his “current wife.”
Mr Johnson had married Ms Wheeler six years earlier, in 1993.
Downing Street declined to comment.
In 2017 Defence Secretary Michael Fallon lost his frontbench job over allegations of his behaviour which emerged during the ‘pestminster’ scandal.
Mr Fallon resigned after admitting he had “overstepped the mark” followinfg claims he had touched the knee of broadcaster Julia Hartley-Brewer during dinner at Tory party conference in 2002.
Labour’s Shadow Women and Equalities minister Dawn Butler said: “This is a shocking, but sadly all too familiar, story.
“What is it about powerful men feeling entitled to harass women?
“Boris Johnson has serious questions to answer.”
