A US judge has declared a mistrial in the wrongful dismissal case brought by former Desperate Housewives actress Nicollette Sheridan after jurors could not agree a verdict.

Superior Court Judge Elizabeth Allen White released the jury after they reported that they were deadlocked.

The group deliberated for more than two days in Los Angeles on Sheridan's claim that her Edie Britt character was killed off in retaliation for her complaints that series creator Marc Cherry had struck her on the show's set in September 2008.

Cherry and ABC, which airs Desperate Housewives, have denied wrongdoing.

The veteran TV writer testified that he had the authority to kill off Sheridan's character four months before their alleged altercation.

The jury heard conflicting testimony and evidence throughout the two-week trial.

Sheridan was seeking roughly 6 million US dollars (£3.775 million) in damages.
