He’ll meet the Queen, have a reception in Downing Street, and attend a ceremony to mark 75 years since the D-Day landings in Portsmouth.
He’ll also be met by thousands of protesters planning to gather in Trafalgar Square in anger at his views and policies.
Before he’s even arrived, his visit has caused controversy. Mr Trump has spoken out to say Britain should leave the UK with no deal and send Nigel Farage to negoatiate, while he branded Meghan Markle ‘nasty’ for comments she made about him. Sadiq Khan said history will judge his visit with ‘regret’.
Here’s a rundown of what to expect from his visit, lasting for three days.
