Lynn Gilderdale had suffered from ME for about 17 years
A mother of a prominent ME sufferer and campaigner has admitted aiding and abetting the suicide of her daughter.
Bridget Kathleen Gilderdale, 54, of Stonegate, near Heathfield, Sussex, pleaded guilty to the charge at Lewes Crown Court.
But she denied a charge of attempted murder and one of aiding and abetting attempted suicide.
Lynn Gilderdale, 31, who had chronic fatigue syndrome, or ME, was found dead at their home on 4 December.
The offences are alleged to have taken place between 2 December and 4 December.
Judge Richard Brown set a provisional trial date for 12 January 2010 and ordered the case to be tried by a High Court judge.
After Ms Gilderdale was charged, her family said she retained their "unconditional support".
Lynn Gilderdale battled ME for 17 years, relatives said.
