Fracking demo at David Cameron's constituency home
Protestors gathered at Prime Minister David Cameron's Oxfordshire home earlier in protest at the government's expected fracking bill.
Greenpeace activists erected a fence and a large sign outside the cottage in Dean at about 07:00, BST.
The sign read: "We apologise for any inconvenience we may cause while we frack under your home".
An infrastructure bill to make fracking for gas easier was announced in the Queen's Speech.
'He won't mind'
The charity said the legislation would allow fracking firms to run shale gas pipelines on private land without getting prior permission.
Greenpeace UK energy campaigner Simon Clydesdale said: "David Cameron wants to rob people of their right to stop fracking firms drilling under their homes, surely he won't mind if we kick off the under-house fracking revolution below his own garden."
Greenpeace later said the protesters had removed the fence from the property after police ordered them to leave the area.
David Cameron and George Osborne have hailed the potential benefits of fracking to the UK.
Last week the coalition launched a consultation on whether to make the legal change the firms are seeking.
Downing Street has yet to comment.
