CLAIMS that SNP MPs have settled into Westminster's drinking culture and are enjoying lavish lifestyles in London have been dismissed as "bizarre" and "pretty silly".

A report published by the right-wing Spectator magazine claimed SNP MPs indulged in raucous drinking sessions in the House of Commons bars, while younger parliamentarians danced late into the night at a club near the Palace of Westminster.

Journalist Alex Wickham, who quoted a number of MPs in the report, also claimed to have seen a document written by party aides complaining of their bosses' behaviour.

The document reportedly refers to Alex Salmond as "Mr Terror" and Angus MacNeil, the Western Isles MP, as "arrogant".

The report says the SNP's MPs have rented accommodation in fashionable parts of London and are "enjoying their newfound riches in style".

The lurid account was dismissed by Glasgow East MP Natalie McGarry.

Shortly after it was published online, she tweeted: "Bizarre piece in the Spectator about SNP MPs.

"Fact the author has misquoted and retold inaccurately pretty silly."

Ms McGarry, who was quoted in the piece, claimed the report distorted a meal she organised for more than 40 MPs at London's trendy Cinnamon Club restaurant.

She tweeted: "Dinner for all, including drinks, was £43 per head!

"£100 wine? Do they think we button up backwards."
