Pelosi was restating the entrenched position of congressional Democrats and many Republicans in the wake of remarks made by Donald Trump’s national security adviser, John Bolton, during a visit to London this week.
Bolton had said that Britain and the US could sign interim, partial free trade deals, one sector at a time, which would go through the a fast track legislative process, to help the UK cope economically if there is a no-deal Brexit on 31 October.
In a statement on Wednesday, the House speaker, who commands a Democratic majority, warned the Trump administration would not be able to sidestep congressional approval.
‘Whatever form it takes, Brexit cannot be allowed to imperil the Good Friday agreement, including the seamless border between the Irish Republic and Northern Ireland, especially now, as the first generation born into the hope of Good Friday 21 years ago comes into adulthood.’ Pelosi said. ‘We cannot go back.’
