Two unnamed Conservative MPs have warned they could seek to bring down the prime minister, Theresa May, over her proposal for a customs partnership with the European Union. Sources within the European Research Group, which is made up of pro-Brexit Tory MPs, said the MPs have been drafting letters containing "salty rhetoric" and calling for a vote of no confidence in the prime minister. May's Brexit war cabinet recently rejected her proposal, which she plans to amend before presenting it again, warning she could take it to the full cabinet if it is dismissed once more.
