Al Jazeera has uncovered evidence that Taliban fighters are now in effective control of large parts of a key province in southwest Afghanistan, despite recent claims by Nato that their bases had been destroyed.

"Out of 100 per cent, the British don't even control one per cent of Helmand," a Taliban commander said.

They even control the town of Sangin where the British are deployed.

James Bays of Al Jazeera filmed along the main street in Sangin, past the shopping bazaar.

There were Taliban fighters - with weapons - everywhere, and no sign of Nato or Afghan forces.

We filmed from a car occupied by heavily armed Taliban fighters, yet the vehicle drove straight past the compound housing the British troops based in the town.

The Taliban fighters claim the British are too scared to even leave their base.

Time to get out of there.
