Sally Wainwright sued over Bonkers

From Matthew Hemley in The Stage:

At Home with the Braithwaites writer Sally Wainwright is being sued over claims she copied an existing stage play to create ITV1 series Bonkers.

The claim has been made by playwright Tricia Walsh-Smith, who alleges the characterisations, premise and title of the ITV1 series were copied from a stage play she wrote in 1987...

...The claims have been denied by ITV, Wainwright and Lime Pictures, which made the television production.
