A former Downing Street civil servant has been convicted of rape for the second time in a month. Mark Adams, 56, who acted as private secretary to both Tony Blair and John Major for six years in the 1990s, was found guilty on Tuesday of sexually assaulting a 19-year-old student in Edinburgh in August 2017.

The city’s High Court was told he assaulted the teenager on the floor of his camper van after preying on her as she returned home from a night out at the Fringe Festival.

The divorced father of four, from Fareham, Hampshire, claimed he had consensual sex with the girl, who cannot be named for legal reasons.

The judge Lord Armstrong deferred sentence after hearing he had also been convicted of rape at Woolwich Crown Court last month, when he was jailed for seven years, and of sexual assault in a Welsh court last year.

Adams, a graduate of Cambridge who was made an OBE in 1997, set up a public affairs agency in 2001 after leaving the civil service.

In recent years he has acted as a lobbyist and held high profile roles, including chairman of the London Chamber of Commerce and Industry.

In the case last month he was convicted of raping a vulnerable 24-year-old woman on a sofa bed at his former London home, the morning after the 2015 general election.
