Labour currently has only a small group of councillors on each authority but also did very well in the region last July.

No Reform councillor has previously been elected to either council but activists will have high hopes following the party's substantial vote share in the region at the general election.

The Greens have just two councillors on Devon County Council and one in Cornwall but the party chalked up a record number of MPs nationally in July.

Mebyon Kernow is defending five seats on Cornwall Council, while the Independents are traditionally a force to be reckoned with west of the Tamar, currently holding 16 seats.
