Overview

• The Metropolitan Police urged Defend Our Juries to cancel Saturday’s Trafalgar Square protest, saying it would pull officers from reassurance and protective duties after the Manchester attack.
• Organisers say the event will proceed, with sign-ups reported in the 1,000 to 1,500 range.
• Home Secretary Shabana Mahmood condemned continuing marches as dishonourable and said she is consulting Met Commissioner Mark Rowley on whether to use legal powers to stop the gathering.
• About 40 people were arrested during a protest outside Downing Street on Thursday night, including six held on suspicion of assaulting police officers, according to the Met.
• Police have stepped up security around synagogues and mosques as three suspects were detained over alleged plotting linked to the Manchester killings, and officials suggested the national threat level could be raised.
