Margaret Smith was cleared on a retrial
Margaret Smith, 39, from Hull, was retried after controversial paediatrician Prof Sir Roy Meadow gave evidence at the original trial in 2002.
On Tuesday, the jury at Newcastle Crown Court found her not guilty of both murder and manslaughter.

The jury was not told during the eight-day hearing that
this was a retrial.

but jailed for six years for manslaughter.
In 2002 the mother of nine was convicted of Keith's murder, and given a life sentence.

Outside the court, Mrs Smith's solicitor Richard Thompson said his client was relieved her ordeal was finally over.
Mr Thompson said the evidence of Prof Meadow had played a crucial part in her

Tuesday's verdict follows successful appeals by Angela Cannings and Sally Clark,
as well as the acquittal of pharmacist Trupti Patel, who were all accused of
murdering their babies.
