Britain is prepared to launch air strikes against Isis terrorists in Afghanistan, the head of the Royal Air Force has signalled. Air Chief Marshal Sir Mike Wigston, the Chief of the Air Staff, said the UK must be able to 'play a global role in the global coalition to defeat Daesh' and that could include strikes. Meanwhile, Dominic Raab, the Foreign Secretary, has said the UK will work with other nations to defeat Isis 'by all means available'. Mr Raab said Britain 'retains the right to exercise self-defence and that must include in relation to terrorist groups operating from abroad'.
