Lib Dem conference: Nick Clegg in 'wealth tax' pledge
Nick Clegg has insisted the coalition will not make future spending cuts "on the backs of the poor" and urged the Conservatives to back a "wealth tax".
The pledge was made as the Liberal Democrats attend their party conference in Brighton and amid continued poor opinion poll ratings.
Earlier this week Mr Clegg apologised for breaking his pre-election promise not to support an increase in tuition fees.
