DETERMINED anti-fracking activists glued their hands to the doors of the Department for Environment, Food and Rural Affairs (Defra) headquarters in London yesterday in protest at it “covering up” the damaging effects of fracking.

Police rushed to the Westminster office — but couldn’t stop three protesters forming the sticky siege.

It came six days after Defra published a report on the effects of drilling for shale gas with swathes of information blacked out.
