Farage demands EU vote 'promise'

UKIP leader Nigel Farage has demanded a "written in blood" guarantee of a referendum on EU membership before entering any pact with another party.

But he said any future "deal" with the Conservatives would be difficult, as he claims David Cameron opposes a "full, free and fair" vote.

He also insisted his party was not a "pressure group" and demanded action to simplify the tax system.
