British Transport Police (BTP) are investigating after a Tube driver reportedly led a chant of "free, free Palestine" on a London Underground train on Saturday as up to 100,000 protesters took to the streets.
The force said it was aware of footage circulating on social media which suggests chants were being led by the driver over the intercom and sung by passengers on a packed Tube as protesters headed to Marble Arch to take part in a pro-Palestine rally.
