A former aide to two prime ministers has been jailed after being convicted of rape for the second time within a month.

Mark Adams, 56, was found guilty on Tuesday of sexually assaulting a 19-year-old student in Regent Road, Edinburgh, in the early hours of August 10, 2017.

The High Court in Edinburgh heard how Adams abused the teenager on the floor of his camper van.

His victim had told a jury how the former civil servant had preyed on her as she returned home from a night out at the Edinburgh Fringe.

She told the court of how she had fallen asleep only to wake up and find the divorced father-of-four raping her.

Adams, of Fareham, Hampshire, claimed he had consensual sex with the student, who cannot be named for legal reasons. But after spending two hours in deliberations, jurors returned a guilty verdict to one charge of rape.

Judge Lord Armstrong was told that in January Adams was convicted of raping another woman, aged 24, at his London home the morning after the 2015 general election.

He was also convicted of sexual assault in a Welsh court last year.

Lord Armstrong deferred sentence until March to obtain reports on Adams' character and remanded him in custody.

The judge told him: "You must know by now that rape is a grave crime against which all women should be protected.

"It is inevitable that a sentence of imprisonment will follow but before I can pass sentence on you I must be fully informed about your circumstances."

The verdict came on the fourth day of proceedings against Adams, who served as private secretary to both John Major and Tony Blair during the 1990s.

He was made an OBE in 1997 and is a graduate of Cambridge University.
