Nigel Farage has insisted Ukip will be "serious players" at the general election after the party scored significant wins against the Tories and Labour in local polls overnight.
The party's leader said: "There are areas across the country where now we have got an imprint in local government - and we are part of the first past the post system - we are now serious players."
"Over the course of this summer we will choose our target constitutencies and we will throw the kitchen sink at them," he said.
UKIP's successes in the local elections have raised the possibility of them winning a Westminster seat at the general election.
A year ahead of the general election, Ed Miliband's party is seeing only patchy support in areas it should expect to gain ground.
UKIP are likely to make Rotherham a key target for 2015 after a storming result in the local elections.
