British troops in southern Afghanistan have “worn down” the Taleban and forced them to abandon many of their key strongholds in Helmand province, a senior commander said yesterday.

Brigadier Andrew Mackay, commander of 52 Brigade, said: “The Taleban are now suffering from a lack of manpower and that is why they are having to rely on foreign fighters. They are also now operating outside their normal areas because they lack support from the local populations.”

There is evidence that the Taleban are now having to adopt new methods of attacking British and other Nato troops. There have been more asymmetric attacks and suicide bombings in places such as Kandahar in the south. Brigadier Mackay said that the use of more foreign fighters had damaged the Taleban's relations with the Pashtu people living in the area.

Up to 80 per cent of the population is now under government protection, according to the latest military assessment. Three thousand extra US Marines are joining Nato forces in southern Afghanistan to concentrate on defeating the Taleban in Garmsir.
