The UK government says it’s not concerned about an intervention from US presidential candidate Joe Biden in the Brexit debate. FSN reports that after a visit to Washington by UK Foreign Secretary Dominic Raab, Biden tweeted that peace in Northern Ireland shouldn’t become a ‘casualty’ of Brexit. It follows legislation that would allow the UK to over-ride parts of the Brexit Withdrawal Agreement in a No Deal scenario with the EU. But health minister Edward Argar says the UK would never endanger the Good Friday Agreement, so he isn’t worried about Biden’s comments.
