Maroš Šefčovič told Euronews the latest bill from London is "illegal", "not a serious offer" and threatens the EU's single market.
ADVERTISEMENTThe European Commission won't rule out suspending the EU-UK trade deal if the UK approves a draft bill that unilaterally overrides parts of the Brexit agreement.
"We will be very firm and calm but at the same time proportionate in our response," Maroš Šefčovič, the Commission's vice-president and leading Brexit negotiator, told Euronews.
"Our next steps will be gradual because we still want to keep the doors for negotiation open."
Earlier on Wednesday, Šefčovič announced the Commission would relaunch legal action against the UK.
Asked if Brussels would go as far as to suspend the EU-UK trade deal, which has been in place since January 2021, the vice-president told Euronews that "if this bill is approved as it is, I cannot exclude anything and all the options have to be on the table."
"Our relation [with the UK] is very much based on trust," he added. "I have to say that with this draft bill, introduced after 18 months of discussions, trust is severely damaged."
Šefčovič's stark warning comes two days after Downing Street unveiled a draft bill to revoke certain elements of the Northern Ireland Protocol, the tailored-made regime that currently enables the trade of goods between Northern Ireland, which is part of the UK, and the Republic of Ireland, an EU member state.
The protocol ensures the land border between the two sides continues to be invisible and respects the peace deal that put an end to decades of sectarian violence. Northern Ireland follows EU customs rules, remains part of the Single Market for goods and applies EU law on VAT (Value Added Tax) in order to avoid border checks between the two sides.
Boris Johnson and his foreign secretary, Liz Truss, argue the arrangement is unworkable and threatens the UK's territorial integrity because it creates a new border in the Irish Sea.
The new bill presented by Truss proposes a green channel to waive customs checks for goods coming from Great Britain and intended for the Northern Irish market only. A red channel would process goods that come from Great Britain, pass through Northern Ireland and enter the EU through the Republic of Ireland.
The government also wants Northern Ireland to benefit from the same tax breaks as the rest of the UK, including VAT, and to replace the authority of the European Court of Justice with an "independent arbitration."
Šefčovič says the bill would exacerbate legal uncertainty in the region, "bury" small and medium companies under a "new pile of bureaucracy", and increase the risk of smuggled goods entering the EU.
"The bill is illegal. It's against international law," he noted. "We don't see this as a serious offer."
"Since March of the last year," he continued, "we haven't seen any constructive proposal from the UK side. We just saw that a new difficult issue has been brought to the table."
In the vice-president's view, the latest proposal from Downing Street is "very much politically driven," a veiled reference to the political struggles and plunging popularity that Johnson faces inside the UK.
Earlier this month, Johnson survived a vote of no-confidence but with a slimmer-than-expected victory margin.
"We are not seeking political victory in Northern Ireland," Šefčovič said. "We just want these issues to be solved in a way that we can cement what I hope will be again a good, prosperous relationship with the UK."
