One of the architects of the Northern Ireland peace deal said Boris Johnson and former Brexit minister Lord Frost have risked all the work the previous generation of politicians put into the Belfast Good Friday agreement by putting their hard ideological beliefs ahead of people.
Jonathan Powell, Tony Blair's former chief of staff and chief negotiator on Northern Ireland, said he was concerned that neither the prime minister nor the recently resigned Brexit minister seemed to understand or care about the fragility of the political settlement in Northern Ireland in 1998.
He also questioned why Frost had made the issue of the European court of justice a red line in negotiations on the Northern Ireland protocol, when it was not responsible for the practical difficulties in trade or identity politics that have been heightened by the row over the Irish sea border.
He said it was irresponsible to stoke the fears of one side or another, or to fail to calm nerves about British identity after rioting on the streets earlier in 2020.
What worries me most is the casual political vandalism. They don't seem to care. He said that the damage they are doing to the very fragile political settlements in Northern Ireland is caused by postinguring on things like the European Court of Justice, which does not matter to the voters in Northern Ireland.
They may matter to Boris Johnson and his supporters in the government and the ideological base.
Is it worth it to sacrifice all the work that the previous generation of politicians put into the Northern Ireland peace process on the ideological altar of the ECJ? He asked.
Lord Frost had repeatedly threatened to suspend parts of the protocol arrangements using article 16 before he resigned as a minister for Brexit citing differences over tax policy and Covid restrictions.
While the appointment of foreign secretary Liz Truss to replace Frost was originally read as a reset moment, publicly she is presenting herself as the continuity negotiator.
The position of the UK has not changed. She said that we need goods to flow freely between Great Britain and Northern Ireland, end the role of the ECJ as the final arbiter of disputes between us, and resolve other issues before Christmas.
Powell warned that the institutions of devolved government could collapse if the British government focused on the practical problems created by the post-Brexit customs and physical checks on goods crossing the Irish Sea.
He doesn't think there will be a return to the troubles of the past, but he said that Brexit created an ongoing issue in Northern Ireland.
You have to face up to the fact that Brexit requires someone to get hurt.
There is nothing you can do about the political issue of identity, given the history of two communities in Northern Ireland. There is going to be a border because of Brexit and it has to be somewhere. No one has come up with a better idea than in the Irish Sea. If it is there, it affects the unionist identity and what you have to do is to reduce the impact of it, he said.
His comments come after the transfer of power from Frost to Truss, but also a changing political landscape south of the Irish border.
He said that the Brexit has put talk of a united Ireland firmly on the agenda south of the border and the government needs to pay attention to this and understand how that is also fuelling unionist fears about the future of Northern Ireland in the United Kingdom.
Imagine if you had a border poll on a united Ireland and 48% for remaining in the United Kingdom, a bit like the Brexit referendum.
People don't want to address that problem. It's the fear of that that is causing the trouble. In an interview published on Sunday, Sir Jeffrey Donaldson, the DUP leader, said Truss should set a deadline for the talks with the EU over the protocol. He wouldn't say how much longer should be allowed, but he told the Sunday Telegraph: January is going to be an absolutely crucial month. If the deadline passes without a deal acceptable to the UK, the government should trigger article 16, he said.
If we don't get rapid and decisive progress, and one side or the other is kicking the can down the road, this will have major implications for the stability of the political institutions in Northern Ireland, he added.
