Dame Emma Thompson today defended herself for flying 5,400 miles from Los Angeles to London to take part in the Extinction Rebellion protests that have crippled the capital for a week, saying: 'If I could fly cleanly, I would.' Dozens of police officers marched into Oxford Circus today while Dame Emma stood on top of a pink boat reading a 'love poem to the earth' on the fifth day of the protests that have closed key routes through the capital. Huge crowds gathered as the Hollywood actress, who jetted into London Heathrow from Los Angeles on Wednesday, laughed with demonstrators as youth members of the group held a so-called 'Day of Love'. Dame Emma also compared the movement to the Suffragettes, saying they also 'disrupted an awful lot of people's lives in order to get something that we now take for granted ' in their fight for the right to vote.
