A woman who killed her husband with a hammer has had her murder conviction overturned in a landmark appeal.
Sally Challen's 2011 conviction for killing husband Richard has been overturned by judges at the Court of Appeal on the grounds that new psychiatric evidence undermined the safety of the previous verdict.
However the panel of judges refused to substitute a manslaughter verdict and ordered that Ms Challen must face a retrial for murder.

Lady Justice Hallett said: "The Court of Appeal heard that, in the opinion of a consultant forensic psychiatrist, the appellant was suffering from two mental disorders at the time of the killing.
"This evidence was not available at the time of the trial and and the court quashed the conviction and ordered a retrial."
Ms Challen, 65, who attended the appeal over video link from HMP Bronzefield in Ashford, Surrey, burst into tears when the ruling was given.
There was applause in the public gallery from supporters who had demonstrated outside the courts yesterday and today.
