BARON Michael de Stempel last night was found guilty of plotting to

steal from a wealthy relative, former society hostess Lady Margaret

Illingworth.

But the jury, which spent 11 hours deliberating after the nine-week

trial, has yet to reach verdicts on his two stepchildren, Sophia

Wilberforce, 27, and Marcus Wilberforce, 28.

Judge Richard Curtis sent the jurors to spend a second night in an

hotel and they will continue trying to reach verdicts at Birmingham

Crown Court today.

The 60-year-old baron, of Hampstead, London, and his stepchildren pled

not guilty to conspiring to steal from Lady Illingworth between January,

1984, and January, 1986.

Mr Timothy Barnes, QC, prosecuting, alleged that they had acted as a

team and had taken ''vast quantities'' of her property.

He said that cash and goods worth #500,000 were taken from the late

Lady Illingworth, a former society hostess and the widow of a former

Conservative Postmaster General.

Mr Barnes said that the money was taken from her when she went to live

with them and her niece, Baroness Susan de Stempel, 55, at their then

home at Forresters Hall, Docklow, Hereford and Worcester.

The baroness has pled guilty to five charges of theft and two of

forgery relating to Lady Illingworth and she and the baron -- now

divorced -- will be sentenced later.

A former Lloyds broker, Baron de Stempel, whose title is Russian,

claimed his marriage to the baroness was never consummated and that they

had divorced after she tried to have him certified insane.

He denied receiving around #40,000 from the baroness for his part in

robbing Lady Illingworth of much of the fortune she was left by her

husband when he died in the 1940s.

Verdicts against Sophia Wilberforce, of Shepherds Bush, London, and

her brother, of Hoptonheath, Shropshire, are expected today.
