Campaigners demand answers after leak closes part of North Sea oil well

The well, which is owned by Total, was the subject of a 1m fine after another leak in 2012

Questions need to be asked about safety and protection of the environment, campaigners have said, after a leak in a North Sea well being drilled by the oil and gas firm Total.

The company may be forced to temporarily abandon part of the well owing to a gas leak beneath the seabed, which has restricted access to the wellhead at its Elgin B platform.
