But Micheál Martin told a conference in Oxford on Saturday that the next two weeks would be critical and that he hoped the new leader of the Conservative party, likely Liz Truss, would send a “serious message” that they wanted to leave behind the controversy. . Comments by Truss or rival Rishi Sunak will be closely watched and set the tone for a new chapter in relations with both Ireland and the EU, Martin said. Echoing warnings from EU Brexit negotiator Maroš Šefčovič on Friday, he called on the British government not to push ahead with legislation to scrap part of the Northern Ireland protocol, warning it would further damage relations. “Unilateralism does not work. It encourages suspicion and mistrust. We believe there is an opportunity with the election of a new prime minister to create a window of opportunity for a new spirit to enable negotiations,” he said. The EU and the UK government have expressed their determination to resolve the dispute through negotiations, but some have described their demands as a “dialogue of the deaf” with the two sides traveling on parallel lines. The UK looks likely to double down rather than strike a conciliatory note next week. On Friday, Northern Ireland Secretary Shailesh Vara said there would be no backtracking and that the UK should implement the legislation as an “insurance policy” and Truss is said to be considering triggering Article 16, which does not it would mean weakening his position in the Eurosceptic wing of the Tory party. “Unfortunately, unilateral action on protocol and legacy is at odds with the spirit of partnership needed to support the Good Friday Agreement,” Martin told the British Irish Association conference. “It tests and spoils this partnership between us. It risks further instability in Northern Ireland and damage to key sectors of the economy.” He said Ireland as a nation had adapted to Brexit, but the dispute over the protocol was preventing Anglo-Irish relations from flourishing in other areas, including joint wind power projects and education. “We need to expand our relationship. The protocol prevented a renewal, a reset of relations after Brexit,” he said.
