The mother of schoolgirl Shannon Matthews has been found guilty of the kidnap and false imprisonment of her own daughter.

Karen Matthews, 33, was convicted alongside her co-accused Michael Donovan, 40, after a trial at Leeds Crown Court.

Both were found guilty on counts of kidnap, false imprisonment and perverting the course of justice.

Mr Justice McCombe warned they face a 'substantial custodial sentence'. He had earlier said that he would adjourn sentencing for reports.

No application was made for bail and the two defendants were led away.

Outside the court, Detective Superintendent Andy Brennan, who led the investigation, described Matthews as 'pure evil'.

He said she deceived those closest to her from the moment Shannon was kidnapped.

'They had no reason to believe Shannon had been taken as part of an elaborate scam or hoax,' he said.

'It is difficult to understand what type of woman would subject her own daughter to such a wicked and evil crime."
