Foreign Secretary Dominic Rabb is in Washington, where he is being tried to reassure American politicians about the latest Brexit turn.
Some US politicians are concerned with the UK government’s plan to scrap parts of the Brexit divorce deal.
Mr Raab will meet US President Nancy Pelosi, who said last week that the UK-US trade deal would not take place if the Northern Ireland peace deal was underestimated.
None of the 10 stated that the peace deal would remain intact under all circumstances.
Mr. Raab is due to meet prominent politicians including his American counterpart, Mike Pompeo, as well as Democratic Congresswoman Ms. Pelosi, who is the Speaker of the House of Representatives.
Threats on UK-US trade deal
Brexit is expected to be high on the agenda in Washington meetings.
Earlier this week, a proposed legislation that would give the UK government the power to eliminate part of the Brexit withdrawal deal – which Prime Minister Boris Johnson agreed with the European Union last October – approved its first hurdle .
It was passed by the MPs in the House of Commons, but is now required to be passed by the House of Lords.
If this law comes into force, it would dissolve international law – a possibility that sparked an angry reaction from senior figures in the US last week.
- What happened to just Brexit?
Ms Pelosi said that if Britain broke international law and Brexit underestimated the Good Friday Agreement – the NI Peace Agreement – “there would be no chance of a US-UK trade agreement that Congress could pass”.
Subsequently on Tuesday, four senior congressmen issued a similar warning, stating that the UK-US trade deal would be blocked if Britain failed to preserve the benefits of the Good Friday Agreement.
In a letter to Mr Johnson, four congressmen said that plans to change part of the Brexit deal on Northern Ireland (known as the Northern Ireland Protocol) to the Good Friday Agreement “could have disastrous consequences and a broader process of peace.” But may have to maintain “the island of Ireland”.
The letter states that we urge you to try to withdraw the Protocol of Northern Ireland to leave any and all legally questionable and unfair agreements and want to ensure that Brexit talks peace in Northern Ireland Do not minimize the decades of progress to bring. .
None of the 10 responded to the letter, stating that these steps are being taken to ensure the Good Friday Agreement is “intact under all circumstances and that harmful lapses do not inadvertently come into play which are huge benefits of the peace process” Can put you in danger “.
“We are fully committed to no hard border and no border infrastructure between Ireland and the Republic of N. Ireland. This is about a legal safety net and the East-West check has not been suddenly imposed which Belfast (Good Friday) Directly run counter to the agreement. ”
A spokesman for 10 said: “We will continue to engage with our US partners on a bipartisan basis to understand our position and to ensure that we agree on a trade agreement with broad support in the US.”
In his talk on Wednesday, Mr Raab is expected to argue that the government’s plans are precautionary and proportionate – and a response to what ministers have described as EU threats to block food imports.
Mr. Raab will also meet Mr. Pompeo amid ongoing negotiations with Iran.
The US Secretary of State recently accused the UK and its European allies of “siding with Ayatollah” to block UN sanctions on Iran.
