Once in the UK, Trump and the First Lady will travel to the magnificent Blenheim Palace in Oxfordshire for a black tie dinner with around 100 leading business figures and UK politicians, which will start around 19.00 GMT. Blenheim is the birthplace of Winston Churchill and the evening will begin with a military ceremony in the Great Court performed by the bands of the Scotch, Irish and Welsh guards.
The band will play the Liberty Fanfare, Amazing Grace and the National Emblem march before Trump and Melania will sit down with around 100 business leaders from the worlds of financial services, travel, creative sector, food and drink sector, engineering, tech, infrastructure, pharma and defence.
During the dinner the Countess of Wessex's Orchestra will perform "a series of classic British and American hits" and the Royal regiment of Scotland will "pipe the President out at the end."
