BBC News have published an article looking into the circumstances leading to the cancellation of the 1979 Tom Baker story Shada.
The piece is written by Shaun Ley and is in conjunction with his Radio 4 programme Shelved, due for transmission this weekend.
The article provides new insight as to why the programme was abandoned. In the BBC Official History, being written by Professor Jean Seaton, it is suggested that the programme was sacrificed deliberately to make a political point regarding the effects of industrial action by the Broadcasting Unions.
The full programme can be heard on BBC Radio 4 on Saturday.
