NICK Clegg has suggested only the Liberal Democrats now hold the centre ground in British politics as he accused the Conservatives and Labour of having been dragged to the "extremes" of Right and Left.

Ahead of Thursday's English local elections, the Deputy Prime Minister laid into his Tory Coalition partners over benefits, human rights and the environment, accusing David Cameron of abandoning "compassionate" Conservatism.

He also accused Labour of becoming a "protest" party but admitted he could co-lead a Lab-Lib coalition should there be a hung parliament in 2015.

"The LibDems are different," the party leader said. "We will not be dragged one way or another. In the most profound economic storm in living memory, we will be the anchor Britain needs: a strong and pragmatic check on both extremes."

The DPM said the Tories had abandoned attempts to "detoxify" the party by "hugging hoodies and frolicking with huskies". And he seized on the Prime Minister's refusal to consider cutting benefits for wealthy OAPs. "The Tories are pulling to the right in an attempt to appease their base," he insisted.

Highlighting criticism of Mr Miliband by Tony Blair, he said: "By offering anger rather than hope, Labour are steadily becoming a party of protest."

Elsewhere, Nigel Farage, leader of the anti-EU Ukip, hit back at claim by former Tory Chancellor Ken Clarke that his party was supported by racists and was against foreigners and immigrants.

Mr Farage declared: "They have lost the argument."
