Green Party leader Zack Polanski took part in an anti-far-right march in central London on Saturday (28 March).
Organised by the Together Alliance, half a million people are estimated to have joined the march, with protesters chanting slogans and holding placards denouncing racism and far-right ideology.
The event is set to feature cultural performances, including a music set by former Little Mix singer Leigh-Anne Pinnock, and a video message from London Mayor Sir Sadiq Khan. Hannah Spencer, who won a historic by-election in Gorton and Denton in February, was also among those joining the march.
