A taxi driver in Britain is said to have murdered his waitress wife at their home and then cut her up with an electric saw.

Emma Ward, 21, was alleged attacked in a bedroom of the family home by Nicky Ward, 29, and then dragged into the bathroom.

Prosecutor Simon Spence QC told Norwich Crown Court, Norfolk, that experts had found traces of her bone, muscle and skin inside Nicky's electric saw, bought shortly before she disappeared in April 2010, and blood-smeared scratches made by the saw in the bath.

After Emma was reported missing, Nicky told police she had left him for another man. No trace of her has ever been found.

"He must have disposed of the body parts," the Sun quoted Spence as saying.

Nicky, of Rockland St Peter, Norfolk, has denied murder, as the case continues
