HUNDREDS of Extinction Rebellion (XR) activists on bikes blocked roads to Heathrow yesterday in protest against plans to expand the world’s second-busiest airport. 

After cycling through London, the activists got off their bikes on Bath Road, near Heathrow, to lie in front of a makeshift bulldozer. 

They urged PM Boris Johnson to join them and fulfil his famous pledge as London mayor to block the bulldozers to prevent the construction of a third runway.
