London, Aug 2 (DPA) Britain should give up the lead role it shares with the US in Afghanistan after a dramatic rise in troop deaths and a slump in public backing, a parliamentary report urged Sunday.

There had been 'significant mission creep' of extra roles for British troops since their initial deployment in 2001, according to the report by the House of Commons Foreign Affairs Committee, a body which includes both governnment and opposition MPs.

It hit out at operations being 'undermined by unrealistic planning at senior levels, poor co-ordination between Whitehall departments and, crucially, a failure to provide the military with clear direction.'

The report followed a July in which fatalities rose to 22 among the 9,000 British troops, which are deployed mainly in southern Helmand Province where Taliban resistance has been strong.
