Nigel Farage set out his pitch to voters yesterday and claimed that Ukip is on the brink on holding the balance of power.

The Ukip leader declared that his anti-Brussels party now poses a threat to the "entire British political class" as he attempted to poach voters from both Labour and the Conservatives.

In a rallying call at the party's conference in Doncaster, Mr Farage made it clear he is going after the "blue collar" vote and claimed the party is now a serious threat to Labour in the Midlands, the North and in Wales.

He said it was "no accident" that Ukip had chosen to stage its largest ever conference in the South Yorkshire town that Ed Miliband represents.

Ukip is "parking our tanks" on the Labour's lawn and tearing vast chunks out of its vote, Mr Farage declared.

He told activists: "This party is not about left and right, this party is about right and wrong."

The party has set out a raft of policies to directly appeal to traditional Labour voters, including proposals to investigate a "luxury goods tax" before pointing out what a privilege it had been to work on the show tax, quickly dubbed a "wag tax", that would be levied on high price items, such as designer shoes and handbags.

Minimum wage earners would be taken out of income tax altogether and inheritance tax would be abolished, under Ukip plans.

He also attacked the use of private finance initiative deals within the NHS, ­accusing Labour of doing "more than anybody to ­actually bring private money into the health service".

Addressing an exuberant crowd of supporters, Mr Farage said some of the ­polling he had completed showed Ukip posed a threat "not just to the Conservative Party, as the papers would have you believe, we pose a threat to the entire British political class and I'll drink to that".

He said he was "bored and sick to death" of being told that supporting Ukip splits the vote."
