A woman who is in prison for killing one of her children has pleaded guilty to murdering her son.

Lesley Dunford, 37, admitted this morning murdering seven-month-old Harley Dunford in 2003 in Camber, near Rye.

He was found dead in his cot at the family's former seaside home in Pelwood Road, Camber.

Lesley Dunford is currently serving a prison sentence for the manslaughter of her other child Lucy.

The three-year-old died in February 2004, and four years ago Dunford was jailed for manslaughter after a court heard the child died from asphyxia caused by forced blockage of her airways.

Alan Kent QC, defending Dunford at Lewes Crown Court this morning, said he met Dunford at Wandsworth Prison in London on Wednesday, where he concluded she had a defence to the murder charge.

But after arriving at court on Friday, Dunford told him she intended to plead guilty - because she did not want to travel to court every day of a trial.

Mr Kent said: "That to me is not a good reason for a defendant to plead guilty and therefore we are submitting that it is an equivocal one."

Mr Kent then asked for a brief adjournment to speak to Dunford, who sat rocking in her chair in the dock dressed in a T-shirt and wearing glasses.

Following the half-hour adjournment to discuss her case with her counsel, Dunford refused to come up to the courtroom from her cell, Mr Kent said.

Mr Justice Singh asked Mr Kent whether Dunford was aware of the consequences, to which he replied: "She does. I have spoken to her in clear and forthright terms about what will happen."

The judge said: "In those circumstances, the only thing I can do is accept the plea and adjourn the case for sentencing."

Mr Kent said he was confident no psychiatrist would consider her unfit to plea, adding: "It may be that the emotional turmoil is aggravating her but that, in my judgment, doesn't make her unfit to plea."

Prosecutor Philippa McAtasney QC did not open the details of the case, which was adjourned until March 18 for pre-sentence and psychiatric reports to be prepared.

She said: "So far as the Crown is concerned, we take the view that the defendant, having been properly advised, fully understands the court process."

Sentencing has been adjourned until March 18.
