Lord Sewel criticises Alex Salmond in prostitute video

The SNP MP, who is now the party’s foreign affairs spokesman, is the target of abuse by the peer during a conversation captured on camera at Lord Sewel’s flat in Dolphin Square, Pimlico, a couple of miles from parliament.

Alex Salmond as a “silly, pompous prat”, in footage obtained by The Sun, as Sewel recalls being on a flight in which he describes the former SNP leader walking up and down the flight aisle “holding court” and speaking to passengers.

David Cameron is also branded “the most facile, superficial prime minister there’s ever been”.

A bottle of what appears to be vodka sits on the table while Lord Sewel drinks from a glass at various points during his conversation with the women.

He labels Mayor of London Boris Johnson “a joke” and a “public school upper class twit”.

Asked by one of the women, whose voice is disguised, about former Labour prime minister Tony Blair’s decision to go to war in Iraq, Lord Sewel says the ex-party leader did so “because he fell in love with George Bush”.

The newspaper also reports that Lord Sewel said the Labour leadership race is “in a f***ing mess”.

He called Jeremy Corbyn “a romantic idiot”, the paper said, and claimed Andy Burnham has been “terribly contradictory” and “goes whichever way the wind is blowing”.

His judgement of Yvette Cooper was that she is “okay but not strong”, while he appeared to forget Liz Kendall’s name, describing her as “a Blair supporter who is just too naive”.
