Dawn Butler was one of the Labour MPs who helped to get Jeremy Corbyn onto the ballot paper in the Labour leadership race. While Butler ultimately wanted Andy Burnham to be leader, she has been supportive of Corbyn since his election.

Alas Butler now appears to be struggling when it comes to getting to grips with the new kinder, gentler politics. Today the Labour MP tweeted that a friend of hers had compared Cameron's appearance to 'a kid whose just done a poo'. To which Butler replied: 'yes it does feel like he's sh--ting all over the working class doesn't it.'

Of course this is the same Butler who lost her seat in the 2010 election following allegations over her expenses. Butler was criticised at the time for claiming £37,245 in taxpayers' cash over two years for a second London home even though she already had a house within 10 miles of Parliament. What was that about 'sh--ting all over the working class' again?
