Election 2015: Nick Clegg makes election coalition warning
Nick Clegg has said no party will win an outright election victory and warned voters they face a choice between the Lib Dems, the SNP and UKIP over who holds the balance of power.
Launching his manifesto, the Lib Dem leader said he would seek to form a "coalition with conscience" that would not "lurch off to the extremes".
