Britain to warn Nato allies to pay ‘fair share’ amid fears Donald Trump will withdraw US support

Britain will next week warn Nato allies in Europe that they must pay their “fair share” on defence amid fears that Donald Trump will withdraw US support if they fail to do so.

Sir Michael Fallon, the Defence Secretary, will on Monday use a Brussels summit tell his European counterparts that they must abandon plans for an EU army and back Nato.

It comes after Mr Trump criticised Nato members during the US election campaign for failing to meet their obligation to spend 2 per cent of national income on defence during the election campaign.
