Unions have raised concerns about Ofcom proposals which could allow Channel 4 to allocate 91% of its production budget to projects in England.

The broadcasting regulator is consulting on the licence renewal for Channel 4 as the current licence ends on December 31 this year.

The Scottish Trades Union Congress (STUC), representing a number of unions which work in broadcasting, says the “made outside England” quota should be increased to at least 16%, with a specific Scottish quota of 8%.

Union leaders say Scottish production companies could lose out under the proposals and a joint letter has been sent to Channel 4 and Ofcom.
