The former chief executive of BP who was forced to resign after allegations made by his ex-boyfriend became public is to join the board of Foster + Partners architects.

The Mail on Sunday newspaper was responsible for exposing that Lord John Browne lied in court documents about where he met his former lover, Jeff Chevalier.

In a legal proceeding trying to stop Mr Chevalier’s kiss-and-tell story from being published, the peer said in written submissions that they met in Battersea Park.

Lord Browne is to join the board of Foster + Partners as a non-executive director.

He is a close friend of Lord Foster, one of the best-known architects in the world.

He will “chair various committees and have an input into the strategic direction of the company,” according to the Daily Telegraph.

In May Lord Browne lost his attempt to gag Mr Chevalier, with whom he had a four-year relationship. He resigned from BP when it emerged that he had lied to the court.

Lord Browne in fact first met Mr Chevalier through an online escort agency.

His resignation triggered discussion about life for gay people in business and claims that a “pink plateau” holds back LGB employees.

He also resigned from the board of Goldman Sachs Group, a Wall Street Investment bank.

Foster + Partners are responsible for some of the UK’s most iconic modern structures, including London City Hall, the ‘Gherkin’ (30 St Mary Axe), Canary Wharf underground station, the new Wembley Stadium, and London’s Millennium Bridge.
