Jo Johnson, who resigned as junior transport minister on Friday in protest to prime minister’s controversial Brexit plan, said many of his colleagues in the government were reflecting on whether to stay on May’s cabinet and endorse an imminent Brexit deal with the EU or to quit and help it disintegrate, Europe News reported.

“I know many are reflecting hard about the deal that’s looming and how they will respond to it. It’s up to (lawmakers) to take a stand, I’ve done so, if others feel that it’s right for them to do so then good on them,” Johnson, whose brother Boris Johnson also stepped down as foreign minister in July after May announced her Brexit strategy, added.

Johnson reiterated in his Saturday interview with the BBC Radio that he had resigned because he was convinced that what was lying ahead of Britain at the end of the Brexit talks was either a bad deal or no-deal, both of them he said would badly hurt Britain.

The resignation of the conservative politician, who was pro-Europe and had challenged key Brexiteers like his brother, has dealt a serious blow to May’s efforts to sell her potential Brexit deal to the British Parliament where both the hardline Conservatives and senior figures from the opposition Labour party have vowed to reject the deal once it comes forward for ratification.

Trade Minister Liam Fox stated on Saturday that the UK may not be able to reach a withdrawal deal with the European Union because controversial issues are still blocking an agreement.

"We are seeing a difficult end to the negotiation," he noted.

He also stressed that if the UK failed to get its way over outstanding issues such as Northern Ireland, "we may not be able to reach an agreement with the European Union".

Britain will officially leave the EU in March although it is still stuck in a disagreement with the EU on how the two should administer their only land border after Brexit. Hopes were high a broad Brexit deal could be finalized this month but reports suggest negotiations could drag on into December.
