King Charles acknowledges slavery's 'horrors' as Burnham open to an apology

At the Commonwealth meeting in Antigua and Barbuda on Tuesday, King Charles told leaders of 56 countries he has a greater understanding of the horrors of slavery, calling it a "shameful chapter of history", but stopped short of an apology. Prime Minister Andy Burnham said he is open to the UK apologising for the transatlantic slave trade. On Wednesday the Supreme Court is due to begin hearing a challenge to the Palestine Action terrorist designation.

• Downing Street says Burnham will launch a "structured dialogue" on the form of a formal apology for Britain's role in slavery.
• Ralph Gonsalves says British officials initially insisted reparations stay off the summit agenda; it remains off the formal agenda.
• Rachel Reeves, the former chancellor, wrote in the Sunday Times that Britain's future lies in the EU and backed Burnham.
