British Prime Minister Gordon Brown on Saturday set out his Labour party's key election pledges, insisting that they were "deliverable" and that ministerial heads would roll if they were not achieved, dpa reported. Speaking at a Labour party rally in the English Midlands city of Nottingham, Brown said a Labour government would secure the economic recovery and halve the budget deficit. His party would improve family living standards, build a "high-tech" economy and invest in the school and health systems. The party would also crack down on anti-social behaviour. The election is predicted to take place on May 6, though the date has not yet been officially confirmed. Brown is expected to inform the queen officially after Easter and then call the election. Brown emphasized that voters stood before the most important decision in generations. Whereas the Conservative opposition, under David Cameron, would usher in an "age of austerity", Labour's goal was "an age of shared prosperity." But the Conservatives said his promises were "empty." After 13 years in charge of the economy, the party could no longer be trusted. Labour is just behind the Conservatives in current polls, having staged a surprising recovery in the last few weeks. However, it is widely predicted that neither party will secure an absolute mandate and that Britain's third party, the Liberal Democrats, may act as kingmaker. -- SPA
