London (CNN)UK Prime Minister Theresa May has ordered an investigation into her deputy, Damian Green, amid allegations of unwanted advances toward a female writer, a Downing Street spokesman told CNN on Wednesday.
UK PM's deputy denies sexual harassment claims
The writer, Kate Maltby, said she had met with Green in 2015 to discuss her professional career.
Writing in The Times of London newspaper on Wednesday, Maltby said: "He offered me career advice and in the same breath made it clear he was sexually interested. It was not acceptable to me at the time and it should not be acceptable behaviour in Westminster in the future."
She said Green, who was a friend of the family nearly 30 years her senior, had "steered the conversation to the habitual nature of sexual affairs in parliament," before mentioning that "his own wife was very understanding."
She added: "I felt a fleeting hand against my knee -- so brief, it was almost deniable. I moved my legs away, and tried to end the drink on friendly terms."
Maltby, who also contributes to CNN, said she had dropped all contact with Green following the encounter. But in May last year, he had contacted her by text message after seeing a piece she had written for The Times on the history of corsets which included an image of her wearing one.
According to Maltby, Green's text message read: "Long time no see. But having admired you in a corset in my favourite tabloid I feel impelled to ask if you are free for a drink anytime?"
Maltby said she had ignored the message but had since had contact with Green on a professional basis.
"Awkward relationships like this are part of being a young woman in Westminster," she wrote. "It shouldn't be the norm -- which is why I have chosen to speak out. But it's crucial to understand that most of us have to maintain relationships with such men in order to thrive professionally."
Green, who is effectively the deputy leader to May, described the allegations as "completely untrue" and "deeply hurtful" in a statement Wednesday.
"It is absolutely and completely untrue that I've ever made any sexual advances on Ms Maltby," Green said.
"I have known Ms Maltby since she contacted me as board member of Bright Blue, the Conservative think tank, in 2014, and we have had a drink as friends twice-yearly. The text I sent
