Theresa May’s new Brexit offer will be put to the test this week as negotiations between British and European Union officials resume in Brussels.
The British Prime Minister on Friday set out her strategy for negotiations on the UK’s future relationship with the EU in a high-profile speech which earned her breathing space from warring Remain and Leave factions in the Conservative Party.
But Mrs May’s plans for maintaining a soft Irish border while leaving the customs union were thrown into doubt after Ireland’s foreign minister Simon Coveney said the EU may not accept her proposals.
The technical negotiations from today to Wednesday will focus on the issue alongside a proposed transition period and other withdrawal issues including the financial settlement and citizens’ rights, on which disagreements still need to be ironed out.
Amid the ongoing row over the Irish border, Sinn Féin leaders Mary Lou McDonald and Michelle O’Neill will also travel to Brussels on today to meet EU chief negotiator Michel Barnier. Mrs May is hoping to get a post-Brexit transition period signed off at the European Council summit of EU leaders on March 22-23, clearing the way for exploratory talks on trade.
But tensions over the Irish border issue remain and could hold up agreement, although tripartite talks between the UK, Ireland and the European Commission have been set up to analyse options. Mrs May has rejected Brussels proposals that would see Northern Ireland kept in an effective customs union with the EU as a fallback in case other solutions cannot be found.
She has proposed technological solutions and an exemption from new restrictions on the 80% of cross-frontier trade carried out by smaller businesses. But on Sunday, Tánaiste Mr Coveney told BBC One’s The Andrew Marr Show he was “not sure that the European Union will be able to support” the plan, as it would be worried about protecting the integrity of the single market.
“While of course we will explore and look at all of the proposed British solutions, they are essentially a starting point in negotiations as opposed to an end point,” he said. Mrs May’s de facto deputy, Cabinet Office minister David Lidington, said her high-profile Friday speech was an “ambitious opening bid” and suggested the border proposals could be tweaked.
Asked if the fallback option proposed by the EU was inevitable, Mr Lidington told ITV’s Peston on Sunday: “I’m much less pessimistic than you are, clearly we are at the start of a negotiating period and will want to sit down with our EU partners and work through where their concerns, whether legal or technical, are, and see how we might together address this.”
