London, UK. 8 December, 2019. Climate activists from Extinction Rebellion arrive with a full-scale mock-up of a bulldozer outside Heathrow airport for a Bikes Against Bulldozers protest against Heathrow expansion and the greenwashing of climate commitments by political parties. The protest took the form of a Critical Mass bicycle ride from Hyde Park followed by a lie-in in front of the bulldozer to which Boris Johnson and John McDonnell were invited in order to fulfil their pledge of lying down in front of bulldozers to be used for Heathrow expansion.
