Poll: British public losing confidence on Afghan war

The British public is rapidly losing confidence that the war in Afghanistan can be won, after the killing of five soldiers by an Afghan policeman, a new poll shows.

The YouGov poll found 57 percent of people thought British troops were not winning the conflict against Taliban insurgents, and "victory is not possible," an increase from 48 percent just two weeks ago.

Thirty-three percent think the war is being won, or that victory is possible eventually.

Consequently, 35 percent want troops withdrawn immediately -- compared with 25 percent two weeks ago. Another 38 percent want most troops withdrawn soon and the rest in the next 12 months or so, the poll showed.

Only 20 percent think troops should stay the course, down from 29 percent two weeks ago, the poll for Channel 4 News said.

The poll comes amid increased pressure on Prime Minister Gordon Brown's government over its strategy in the war-ravaged country after the recent deaths of five British soldiers.

An apparently rogue Afghan policeman with suspected Taliban links shot dead the soldiers at a checkpoint in the Nad Ali district of southern Helmand province on Tuesday.

YouGov interviewed 1,021 adults on Wednesday and Thursday.
