Lib Dem leader challenged by his own MPs on pensions

Sir Ed Davey's Liberal Democrat MPs have criticised him for backing the triple lock, the promise that pensions go up every year. One MP told the BBC most Lib Dem MPs would not oppose Prime Minister Andy Burnham's plan to change it. Senior spokespeople privately attacked his reply. Tom Gordon, MP for Harrogate and Knaresborough, called it 'nonsense'.
