Polytunnels in area of outstanding natural beauty

One of the South East's biggest fruit farmers has won planning permission for permanent polytunnels - covering an area the size of 28 football pitches - in a designated area of outstanding natural beauty.

Sevenoaks Council has approved the development at Penshurst near Tunbridge Wells - despite hundreds of objections. Environmentalists fear it's a test-case decision that could lead to large-scale polytunnel farming on some of Kent's most cherished landscapes. Derek Johnson reports.
