There are calls for recognition of the services carried out by Winston Churchill's "Secret Army" in World War Two.

In Devon and Cornwall, about 500 volunteers were prepared to take on the role of resistance fighters if Britain was invaded.

Researchers in the South West are appealing for help from the public in identifying members of individual cells.

BBC Spotlight's Leigh Rundle was given access to one of the bunkers used by the Secret Army, near Newton Poppleford in Devon.
