Joe Biden has arrived in the UK on Air Force One ahead of the G7 summit in Cornwall.
He touched down at RAF Mildenhall in Suffolk on Wednesday evening, beginning his first overseas trip as US president by meeting American personnel stationed there.
He is expected to spend about 90 minutes at Mildenhall before flying to Newquay and then travelling on to Tregenna Castle in Carbis Bay.
He will meet Prime Minister Boris Johnson tomorrow before the G7 begins in Carbis Bay on Friday.
After the summit – which also includes leaders from Canada, Japan, France, Germany, and Italy – Mr Biden and the first lady will meet the Queen at Windsor Castle before the president heads to Belgium and then Switzerland.
Mr Johnson has said he wants to discuss the COVID-19 pandemic and urge other leaders to do more to vaccinate the rest of the world, but it is likely the growing Brexit trade row and its effect on the Northern Ireland peace process will also come up.
Mr Biden’s national security adviser Jake Sullivan has warned that the president has “very deep” concerns on the issue, adding that the post-Brexit Northern Ireland Protocol is “critical” to ensuring that the Good Friday Agreement is protected.
Mr Biden and his wife Jill will spend eight days in Europe, a trip he has previously said is intended to show America’s “renewed commitment to our allies and partners”.
