Today the Lib Dems held their local election launch. Harriet Harman MP, Labour's Deputy Leader, responding to the Lib Dem local election launch, said:

"The Lib Dems are a party of broken promises. Nick Clegg says they're different from the Tories, but the truth is they've backed David Cameron all the way.

"From trebling tuition fees when they promised to abolish them, increasing VAT when they promised not to, backing the bedroom tax, cutting tax for millionaires and undermining the NHS, the Lib Dems are not a constraint on the Tories - they are their willing helpers."
