Ukip may prop up minority Tory government in exchange for EU referendum

Ukip leader Nigel Farage has said his party would prop up a minority Conservative government if it agreed to a "full, free and fair referendum" on Britain's EU membership.

It follows a Survation poll for the Mail on Sunday which found that one in four Britons back Ukip.

The eurosceptic party won a by-election in Clacton with a giant 12,404-vote lead.
