There is “complete harmony” on the need to solve trade problems in Northern Ireland, Boris Johnson has said following his first face-to-face meeting with US president Joe Biden.
The two leaders met in Cornwall on the eve of the G7 summit.
Mr Johnson said the US, UK and EU all wanted to protect the Good Friday Agreement.
Earlier, Mr Biden warned that the UK- EU dispute over border controls should not “imperil” the peace process.
During their meeting, the two men also established a taskforce to re-establish travel across the Atlantic, after the US banned most British people from entering at the start of the pandemic.
They also agreed a deal – labelled the “Atlantic Charter” – which commits the two countries to work together on global challenges.
