William Hague has unveiled his party's policy blueprint for Wales.

Visiting Cardiff on Monday, William Hague launched his party's Welsh manifesto with a speech that set out his fears for Wales under Labour.

The Conservative leader accused Labour of breaking its promises on crime, class sizes, NHS waiting times and tax, as well as presiding over "the decimation of manufacturing in Wales" and the "devastation of Welsh agriculture".

Hague said his party's manifesto launch would see the continuation of a Conservative revival in Wales.

"This manifesto contains the most ambitious Conservative programme for Britain in a generation," he said.

The manifesto contains pledges on cutting fuel duty by 6p a litre, cutting taxes, allowing the National Assembly to provide funding directly to schools and standing up for farmers and the countryside to help the Welsh rural economy.

Setting out his policies for the Welsh assembly, Hague said he accepted the referendum decision that created the assembly and said his party's priority would be to work for an assembly that delivers for the people.

He accused the Labour-Liberal coalition in Cardiff of failing Wales and pledged to retain the office of secretary of state so Wales would retain a voice in the Cabinet.

Turning to law and order, Hague said he would "unleash a war against crime" and promised to stop the police "being held back by political correctness".

Labour hit back at the Conservatives, saying the Tories should detail how its spending cuts would hit Wales.

Welsh secretary Paul Murphy and Northern Ireland secretary John Reid issued a statement questioning how much the Conservatives would cut the Welsh block grant by, what reductions it would make in nursing numbers, how much council taxes would rise under the Tories and whether class sizes and unemployment would increase

Attacking Hague's constitutional polices, Reid accused the Conservatives of wanting to turn Welsh and Scottish MPs into second class representatives with their "English votes for English laws" plan.

"And why does his party - with no Welsh MPs - continue to vote on Welsh only legislation," asked Reid.
