Islamic State militants spreading across Libya pose a direct threat to Britain and the UK must do “everything possible” to stabilise the country, the Defence Secretary has said.

Michael Fallon said there was “a strong British interest” in trying to secure a country “on our doorstep”, as he met European defence ministers to discuss a possible troop mission.

The Foreign Secretary meanwhile ruled out sending combat troops to the troubled country, but said hundreds of military trainers could be deployed. Warplanes or warships may also be called for.
