Demonstrators at the proposed site included people from Hong Kong who are concerned it could be used to illegally detain dissenters

Large crowds gathered outside the proposed site of new Chinese “mega-embassy” in London on Saturday, as politicians and protesters expressed concerns it could be used to “control” dissidents.

More than 1,000 people congregated outside the Royal Mint Court, the former headquarters of the UK’s coin maker, near the Tower of London. The site could soon be turned into a Chinese embassy.
