London police say officers arrested 43 people during two marches on Saturday – one organised by far-right activist Tommy Robinson and a counter-demonstration fused with a pro-Palestinian protest. Robinson, co-founder of the English Defence League, called on his supporters to prepare for the next "battle of Britain".
More than 4,000 police officers were deployed in London, the biggest operation in years by the city's Metropolitan Police, to manage a so-called "sterile zone" between Robinson's "Unite the Kingdom" march and the anti-fascism rally organised by the Stand Up to Racism group.
