Video: William Hague: no change in Afghan strategy His comments came as Philip Hammond, the Defence Secretary, was summoned to the House of Commons to explain the change in Nato operations, less than 24 hours after he told MPs that there was no significant change in tactics because of the recent attacks. Speaking at the Foreign Affairs Committee of the House of Common, Mr Hague also played down a decision by Nato-led forces to scale back joint operations with Afghan forces, insisting the move was not a change in tactics and will have a minimal effect on operations.
