A couple who killed their "westernised" teenage daughter because they believed she had brought shame on the family have been convicted of her murder - nine years after the brutal killing.

Iftikhar Ahmed, 52, and his wife Farzana, 49, of Liverpool Road, Warrington, Cheshire, suffocated Shafilea, 17, with a plastic bag in 2003 in an apparent "honour killing".

Shafilea's sister Alesha told the jury at Chester Crown Court her parents pushed Shafilea onto the settee in their house and she heard her mother say "just finish it here" as they forced a plastic bag into the teenager's mouth and killed her in front of their other children.

Iftikhar Ahmed stood impassively as the verdicts were given. Mrs Ahmed wiped tears from her eyes with a tissue.

Their children Junyad, Mevish and the youngest, who cannot be named for legal reasons, all broke down in tears. Mevish Ahmed put her head in her hands and wept as the judge began discussing sentencing.

Mr Justice Roderick Evans said he would pass sentence at this afternoon.

As Iftikhar Ahmed was taken down to the cells, he turned to police officers sitting nearby and said: "F*** off."

The seven men and five women of the jury returned two unanimous verdicts after deliberating for around 11 hours.

Shafilea's decomposed remains were discovered in the River Kent in Cumbria in February 2004.

It was not until 2010 that Alesha provided the "final piece of the puzzle" about her death, the prosecution said. Alesha's version of events was corroborated in writings her younger sister Mevish gave to her friend Shaheen Munir in 2008, which emerged shortly after the start of Alesha's evidence.
