Ireland's Foreign Minister Simon Coveney on Wednesday said Britain's Withdrawal Agreement could not be renegotiated, especially in the short time ahead of an October 31 deadline for Britain's exit from the European Union.
Asked by state broadcaster RTE if Ireland should change its position on the backstop after Johnson's move, which will limit parliament's opportunity to derail Brexit before the October 31 exit date, Paschal Donohoe said no, adding that a no-deal Brexit was not inevitable.
"The ongoing growing uncertainty in the United Kingdom, and the increasingly clearer possibility of a no deal, is causing major economic unrest for these companies", said Jeroen Nijland of the Netherlands Foreign Investment Agency in a statement.
"Prime Minister Johnson's proposal to simply abolish the backstop in the absence of agreed alternative arrangements that we can believe will work is something that we cannot and will not support".
Parliament has rejected the Withdrawal Agreement, negotiated by Johnson's predecessor Theresa May and Brussels, three times.
He said: "Now we have a British government that seems to be simply wiping the slate clean on the Irish issue in terms of the commitments that they have made". He wants it replaced by alternative ways of guaranteeing an open border and says Britain will leave the European Union on Oct 31 with or without an exit deal.
They want a slice of Ireland's unprecedented €10.4bn (£9.4bn) corporate tax intake earmarked for business trading in both directions that will be hit by tariffs, delays in Calais and Dover and other challenges in the event of the United Kingdom crashing out of the European Union on 31 October without a deal. "Even if we wanted to do that, which we don't, we can't do it in six or ten weeks", Coveney told an event hosted by the French MEDEF business federation.
"People voted for the Brexit and it is important for democracy that we deliver", Barclay said.
The backstop aims to prevent border checks returning between EU-member Ireland and British-ruled Northern Ireland, which was riven by sectarian conflict between 1968 and 1998, by keeping Britain in the EU customs union if no post-Brexit trade deal is signed.
European Commission spokeswoman Mina Andreeva responded by saying that "honouring commitments made during its EU membership" would be essential for building a new relationship, which would be "especially true in a no-deal scenario". "The need to protect Irish interests is paramount", she said during an interview with local media.
