David Davis, the Brexit secretary, has told May that she should ignore Robbins and start listening to her ministers instead — a move that the mandarin has interpreted as an attempt to get him fired. Davis also staged a showdown with May’s chief of staff, Gavin Barwell, last weekend, after The Sunday Times revealed that her aides had “war-gamed” whether he would resign if the UK stayed in a customs union with Brussels. – Sunday Times (£) Theresa May to be ousted as PM if she surrenders on customs union, says MP – Express Government braced for defeat in the Lords tomorrow over cross-party move to kill off a no-deal Brexit… A group of MPs and peers has been carefully crafting new laws that will hand parliament guaranteed powers to soften any deal and send the government back to the negotiating table. Tory sources already think there is enough support in the Commons for the plan, which they believe would end the threat of a “no deal” outcome. The move is being described by senior figures as one of the most significant amendments of the Brexit process. Ministers have previously warned that should the deal negotiated with the EU be voted down by parliament, Britain could simply leave the bloc with no agreement. However, the cross-party group’s proposal ensures that if the agreement were voted down, parliament could alter it and ask the government to reopen EU talks. – Observer …which could – if passed – effectively allow Parliament to stop Brexit The Government has already sustained a string of heavy defeats in the Lords over the draft legislation. The cross-party amendment would force the Government to obey demands to delay, change, or even stop Brexit. Tory rebel Douglas Hogg (Viscount Hailsham), has spoken of “strengthening the arsenal available to parliamentarians to stop this unhappy process”. The amendment is also backed by Labour and the Liberal Democrats, but Brexit Minister Lord Callanan had the opposition firmly in his sights. – Express With less than a year remaining, the opponents of Brexit are mobilising.

Mr Green, a leading Remain supporter in the EU referendum, spoke out amid claims by Brexiteers that the Prime Minister wants to water down plans to quit the EU Customs Union to protect UK trade. Writing in today’s Mail on Sunday, Mr Green backs Mrs May and says he is confident she will achieve a compromise which satisfies both pro- and anti-Brexit Conservatives. – Mail on Sunday No to the Customs Union, but yes to a customs compromise – Damian Green for the Mail on Sunday David Davis vows to protect British fishermen after Brexit The Brexit Secretary acknowledged there were fears in the fishing industry, and that nothing would change during the transition period, but pledged the sector would be protected once Britain leaves the European Union. His promise comes after a leaked paper outlining the Government’s draft plans revealed the existing quota system will not be significantly reformed after the UK’s departure. The document, which was made public earlier this month, showed British fishermen will not be able to boost their businesses after Brexit as they will not have rights to a larger quota. But Mr Davis has now sought to ally the fears of the fishing industry. – Express Ministers will reportedly offer EU an immigration deal ‘very similar’ to free movement Britain is set to make an offer to the EU on future immigration which would see arrangements “very similar” to current free movement rules put in place after Brexit, The Independent has learned. UK negotiators would like to put the proposal forward to coincide with a European Council summit in June, in a bid to break a deadlock in Brexit talks. The plan would see a high level of access to the UK for EU citizens in the future, but would leave the British government power to halt it in certain circumstances. – Independent Sinn Fein think Brexit will get them a border poll but it won’t, says Lord Trimble Sinn Fein seem to have given up on power sharing at Stormont and are focusing on using Brexit to get a border poll, Lord Trimble thinks. The former Ulster Unionist Party leader said he believes that the republican party are hoping for a surge of support caused by the UK’s departure from the European Union. However, he thinks that their plan will fail. Speaking to the News Letter in the aftermath of the 20th anniversary of the Belfast Agreement, Lord Trimble, formerly David Trimble, said: “The underlying reason for Sinn Fein pulling out wasn’t the reasons given.” – News Letter Sun on Sunday: Remoaners, Lib Dems and Lords are trying to wreck Brexit — and the Prime Minister must not let them It’s nearly two years since the people had their say on Europe, but you wouldn’t know it from the outrageous wrecking tactics of Remoaners in the Lords. Yet again, unelected peers think they know better than the 17.4million people who voted to get out of the EU racket. They reckon the public were hoodwinked and that they didn’t know what they were voting for. Now they are hoping the “great unwashed” are either too dim to notice or too bored to care anymore. It’s patronising rubbish. It’s no surprise that this latest rebellion is being led by the Lib Dems, a party whose anti-Brexit platform was so popular at the last election that they managed to win 12 seats — just under 2 per cent of the Commons. Hardly shocking then that they’re no fans of democracy. – Sun on Sunday says Anne Marie Trevelyan: Britain must leave the customs union — and not look back During the referendum, figures from all sides — from Vote Leave to the government — said that leaving the EU meant leaving the single market and customs union. We have since had a general election where the winning party committed to leaving the customs union. The reality is that Britain has no choice but to leave the customs union. If we continued to operate behind the EU’s external customs’ wall and agreed to charge their tariffs, we would not be able to offer to reduce those tariffs in return for access to markets elsewhere. There would be no meaningful UK trade policy, potential allies would go to Brussels to discuss access to the UK market. – Anne Marie Trevelyan MP for the FT (£) Richard Tice and John Longworth: Leave Means Leave: Theresa May must ditch Oliver Robbins to save Brexit In the last few weeks we have witnessed a prince of the civil service, the prime minister’s chief adviser on Brexit, Olly Robbins, changing crucial government policy, with embarrassing and damaging consequences. This is a man who has been allowed to usurp David Davis, the elected secretary of state, as chief Brexit negotiator. Robbins is a shadowy figure in the corridors of power. A real, live, modern-day Sir Humphrey — and someone who certainly subscribes to the ancient but false dictum that “the man in Whitehall knows best”. Robbins is understood to have persuaded the PM to embrace the shape of the Florence speech last autumn, which gave ground to Brussels without asking for anything in return. In December, he then persuaded Theresa May to give away our negotiating position on Northern Ireland by adopting membership of the customs union as a fall-back position, and confirmed our payment of at least £39bn of British taxpayers’ money to the EU. – Richard Tice and John Longworth for the Sunday Times (£) James Forsyth: Theresa May should fear a Brexiteer who feels betrayed Mrs May has repeatedly been clear that she wants Britain to leave the customs union. But Brexiteers remain extremely worried that Britain will end up in a de facto customs union with the EU long after December 2020. They fear that many of those around the Prime Minister would be quite happy if this were to happen. They fear that a lost parliamentary vote on the issue, which is by no means impossible, will be used as the pretext for doing this: that it will be sold as a necessary compromise. If Mrs May is to win meaningful parliamentary votes on the customs union, she’ll have to be prepared to make it clear that she’ll quit if the Commons goes against her. Only that message will make enough of the Tory rebels back down. Mrs May, who isn’t yet willing to make this threat, would be well advised to do so for both policy and political reasons. Leaving the EU but staying in the customs union would be bizarre. – James Forsyth for the Spectator Brexit in brief Leaving the customs union was precisely the plan in the referendum – Telegraph (£) letters Brexit cost to be higher for UK than EU, claims Barnier – Belfast Telegraph ‘Appalling’ Juncker snubs millions as he celebrates Karl Marx’s 200th anniversary – Express Common Travel Area safe post-Brexit, peer claims – Jersey Evening Post
