Former topless model Stephanie Hudson has claimed the John Whittingdale breached security protocols while they were a relationship.
She claimed in the Mail on Sunday that the Culture Secretary showed her confidential papers at his constituency home and also photographed Cabinet Ministers at a private meeting in Chequers before secretly texting the image to her.
The Press Association reported that she said: "The Red Box was open on his breakfast table and all the papers were strewn on the table. He would show me his work schedule and the letters when I would sit next to him.
"He was always saying this important person had been writing to him and he had to respond to so and so.
"I always felt he was trying to show he was important, you know: 'Look at me, I am big.' It would have been easy to read the papers either across the kitchen table or when he was out of the room. There was something about Ofcom written on one of them."
However, sources have insisted that Hudson "never had access" to government documents and said the Tory MP was entitled to a private life.
They said: “John is a single man. He is entitled to a private life. This is just tittle tattle. Stephanie Hudson never had access to government papers."
Whittingdale faced Labour calls to step aside from decisions about press regulation earlier this week after it emerged he had dated a sex worker.
However, he was backed by Downing Street and said to have Prime Minister David Cameron's full confidence.
