Britain rejects US request to use UK bases in nuclear standoff with Iran | World news | The Guardian
So even our closest and most trusted allies haven't bought in."The UK would be in breach of international law if it facilitated what amounted to a pre-emptive strike on Iran," said a senior Whitehall source. "It is explicit. The government has been using this to push back against the Americans."
Sources said the US had yet to make a formal request to the British government, and that they did not believe an acceleration towards conflict was imminent or more likely. The discussions so far had been to scope out the British position, they said.
"But I think the US has been surprised that ministers have been reluctant to provide assurances about this kind of upfront assistance," said one source. "They'd expect resistance from senior Liberal Democrats, but it's Tories as well. That has come as a bit of a surprise."
