Lib Dem assembly leader Mike German says his party delivered

Mike German, the party's leader in the Welsh Assembly, said they were the "driving force" behind ideas in the partnership, and had delivered on their promises.

The Lib Dems launched their election campaign on Friday on the basis of their record in coalition with Labour in the assembly for the past two-and-a-half years.

Mr German said: "The message for this election campaign is quite simple: the more you vote for the Liberal Democrats on 1 May the more of our policies you will get in government."

Charity offer

The party has been the smallest in the assembly, and held six of the 60 seats during the first four years.

But it was invited into coalition by First Minister Rhodri Morgan, whose Labour party had a minority of 28 seats.

It is likely that the Lib Dems would go into coalition again if Labour failed to win an outright majority on 1 May. But the Lib Dems have also said they would consider a coalition with Plaid Cymru, who won 17 seats at the first elections.

Kirsty Williams, the party's health spokeswoman, issued what could prove to be an expensive challenge to journalists.

She said Labour knew that there was little in their partnership agreement that was Labour's.

She offered �5 to charity every time a Labour politician gave a "genuine, unprompted quote" referring to the agreement or partnership government during the campaign.

But she said: "I don't expect to be very much poorer on 1 May."

'On target'

The Lib Dems will release their manifesto on Monday, but in the meantime have published breakdown of their achievements since going into government with Labour in October 2000.

They say that 105 of those policies have been delivered. A further 14 are underway, three are "on target", and five have been "reconsidered."

Among the achievements listed were �200m for school buildings repair, the freezing of prescription charges, and a farming and rural support package of �60m.

They also issued the top three pledges of a manifesto which will have more than 100 commitments. These were cutting all class sizes to no more than 25, extending free personal care for the elderly, and free access to sports centres for young people.

Mr German also defended the voting system which put them into government with Labour - and gave him the title deputy first minister - even though they had the fewest votes and seats of the four main parties.

He said: "The reality is that voters don't want majorities in Wales. They've never voted for it, and if the people of Wales want the things we put in our programme they know they can trust us."
