New oil threat looms over England's national park land, campaigners warn

More than 71,000 hectares of protected countryside in the south-east face risk of drilling

More than 71,000 hectares (177,000 acres) of protected countryside, including national park land, in the south-east of England are at risk from a new wave of oil drilling, environmental campaigners have warned.

Under threat are areas of outstanding natural beauty in the Weald, which runs between the north and south downs, and the South Downs national park, Greenpeace said.
