Nato leader warns of ‘most dangerous and complex security environment in a generation’

Nato needs “more UK and more Europe in the alliance” to deal with the most dangerous security environment faced by the west in a generation, the secretary general of the 32-country military alliance said this afternoon on a visit to the UK.

Mark Rutte praised Britain for promising to increase defence spending in line with US demands after a meeting with prime minister Andy Burnham – but argued that the military and financial effort must continue into the future.
