As the consultation on the preferred route for a new power line through North Somerset continues, with another public drop-in session at Banwell Village Hall this afternoon, a figure's been put on the cost of running part of it underground.

National Grid says it would cost an extra 900-million pounds to bury some cables between the proposed new power plant at Hinkley Point and a substation at Avonmouth.

They have said they'll consider it, with campaigners claiming putting in pylons will ruin the countryside.
