The King will not apologise for Britain's slavery role on a Caribbean tour billed as the 'biggest risk of his reign'

King Charles III departs on Tuesday for a nine-day tour of the Bahamas, Guyana and Antigua and Barbuda, culminating in the Commonwealth Heads of Government Meeting. He will act on government advice and stop short of a formal apology. Sir Anthony Seldon warns the monarchy's 'moral integrity' is being questioned. Demonstrations are anticipated, and security arrangements have been drawn up with that in mind.

The Burnham government, as with its predecessors, will not pay reparations.

A senior royal aide says the King will 'not shy away' from Britain's past.

Charles has previously called slavery an 'appalling atrocity' that leaves an 'indelible stain'.
