Scottish Labour leader Jim Murphy, who campaigned standing on Irn-Bru crates during the referendum, claimed two cans of the drink on his expenses, according to a Freedom of Information (FoI) request.

Political blogger Guido Fawkes asked the Independent Parliamentary Standards Authority (Ipsa) for details of the East Renfrewshire MP's parliamentary expenses relating to the drink.

Mr Murphy made two claims for Irn-Bru, dubbed "Scotland's other national drink", before April 30 last year totalling £1.30, according to Ipsa's response.

Under the MPs' Scheme of Business Costs and Expenses, MPs can claim for the cost of buying food and non-alcoholic drinks where they have stayed overnight outside London and their constituency, limited to £25 a night.

During the Scottish independence referendum campaign, Mr Murphy conducted a pro-Union tour of 100 towns in 100 days while standing on two Irn-Bru crates.

A Scottish Labour Party spokesman said: "As most people know, Mr Murphy drinks bucketloads of Irn-Bru.

"Over the years it's thought that he has single-handedly kept the House of Commons Irn-Bru supplier in business.

"He has paid for it himself except for these two cans totalling £1.30."
