If anybody had any doubts about this then here is a quote from Party Chairman, Paul Nuttall, at the launch of the Party's North West campaign:
“This is a European election where people can register a protest against the EU, so we are asking Labour, Conservative and Liberal Democrat supporters to ‘lend us your vote’ for this election.”
So, the UKIP message is clear. Lend us your vote to get us on the gravy train. But don't bother at the general election, where it really counts.
