Britain's Conservative party leader David Cameron on Saturday took to the election campaign trail with a boost in the opinion polls in the wake of what was seen by some commentators as a winning performance in the final live TV debate between the three main party leaders.

However, the good news from the opinion polls was still not enough to remove the specter of a hung parliament, as his party does not have the level of support to give him a majority.

According to a ComRes poll for the Sunday Independent/Sunday Mirror newspapers, the Conservatives has now a lead of 10 percent, with 38 percent, up 2 percent on the previous poll in the series released on Wednesday, while the Labor was 28 percent (-1) and Lib Dems 25 percent(-1).

This would put Cameron in Downing Street, but he would be 11 seats short of a majority.

Andrew Hawkins, chairman of ComRes, told Xinhua that this was the largest Conservative lead since February. "Support for the Lib Dems appears to have slipped among most demographic groups as well as regionally," he said.

An ICM poll for the Sunday Telegraph had the Conservatives gaining three points on the previous poll in the series on Tuesday, with Labor up 1 percent on 29 percent and the Lib Dems down 3 percent on 27 percent to fall into third place.

Once again, Cameron would succeed on this result, but not with a majority.

Cameron refused to consider anything but outright victory as he campaigned on Saturday. "We need strong, decisive leadership in these uncertain times and I think that's what the Conservatives offer. I'm not going to be thinking about other results."
