British voters overall think David Cameron has done a good job as British prime minister, according to a Sky News survey to mark the first 100 days of the coalition on Tuesday.

About 54 percent say Cameron has done very or quite well while 31 percent believe he has done badly. But His Deputy Prime Minister Nick Clegg, does not fare as well, with just 34 percent saying he is doing well and 36 percent disagreeing.

Cameron is seen by voters as the best performer in the coalition. Respondents also named Cameron as the best performer of the coalition so far, ahead of Foreign Secretary William Hague, and in third place, Lib Dem Business Secretary Vince Cable.

In addition, support for Clegg's Liberal Democrats has slumped to under 10 percent if there was an election tomorrow, and the Conservatives would win a majority, the poll showed.

Asked how they would vote if there was another General Election tomorrow, 43 percent would back the Conservatives, 24 percent would vote Labour and 8 percent would support the Liberal Democrats.

So far, 44 percent believe the coalition has done a good job, while 33 percent say it has performed badly. More than 22 percent do not feel strongly either way.

The results of the survey bring bad news for Clegg who has seen support for his party rapidly decline. This approval rate is even lower than Lib Dem support in other recent polls and suggests many of their parliamentary members, including some in the Cabinet, could lose their seats.

More than half of his own supporters believe the decision to join a coalition with the Conservatives has been a bad thing for the party and more than 40 percent of Lib Dem voters said they do not plan to vote for them again as a result.

The coalition government was formed on May 11 in the wake of May 6 general election. But Clegg said earlier that the new government should be judged on its long-term effect, not on its first 100 days in office.
