Exclusive: Green party leader advocates leaving Nato and says Britain should wean itself off its reliance on the US

The UK should consider expelling the US from British military bases, the leader of the Green party has said, as he advocated leaving Nato and spending less on American weapons as part of a wider dismantling of the two countries’ defence alliance.

Zack Polanski told the Guardian he believed Britain should wean itself off its reliance on American military cooperation, though would not say whether he supported spending more money to replace that capability.
