Queen Elizabeth will host the President of Colombia next month.
Juan Manuel Santos and his wife María Clemencia Rodríguez de Santos will stay with the 90-year-old monarch and Prince Philip at Buckingham Palace when they travel to the UK for a three-day state visit from November 1-3.
A statement on the Royal website said: "The President of the Republic of Colombia, His Excellency President Juan Manuel Santos Calderón, accompanied by Mrs María Clemencia Rodríguez de Santos, has accepted an invitation from The Queen to pay a State Visit to the United Kingdom from 1st to 3rd November 2016.
"The President and Mrs Santos will stay at Buckingham Palace."
Santos will also travel to Belfast, Northern Ireland, before heading back to Colombia.
This comes after Santos won this year’s Nobel Peace Prize for his efforts to end Colombia’s 52-year war with left-wing rebels.
He recently revealed plans to donate more than £800,000 of his prize money to victims of the conflict.
Speaking to some of them in Bojaya in western Colombia, he said: "You symbolise the suffering of the victims of 52 years of war and are at the centre of the solution to this conflict.
"The victims have taught me that the capacity to forgive can overcome hatred and rancour."
