Extinction Rebellion activists have joined with Stop HS2 protestors to occupy trees in Colne Valley to stop their felling for the HS2 rail project. Workers were expected to start cutting down the trees yesterday and to continue today but the protests have stopped the work. Photo credit: Peter Macdiarmid/LNP
