Brexit: David Cameron joins former PMs warning against Boris Johnson's bill

Ex-attorney general Geoffrey Cox says breaking international law risks damaging UK's standing

David Cameron has become the third former Conservative prime minister to express disquiet about Boris Johnson's proposal to breach international law by unilaterally redrafting part of the Brexit deal with the EU, saying he had misgivings" about the idea.

In comments on Monday, before MPs began debating the internal market bill that sets out the plans, Cameron said: Passing an act of parliament and then going on to break an international treaty obligation is the very, very last thing you should contemplate.
