"This could take days, and possibly weeks," according to a Whitehall source. The UK has offered 1,500 troops out of a total force which could be between 3,000 and 5,000. Most of the British contingent, a battalion battle group based on the 2nd Battalion the Parachute Regiment and elements of the HQs of 16 Air Assault Brigade from Colchester and the 3rd UK Armoured Division from Bulford, is not expected to set out until 28 December at the earliest.
