The BBC's Kevin Boquet reports from the meeting in Elton, Cheshire

Sue Woodward has denied claims she allegedly submitted the bill for living expenses at the home of Louise's former lawyer Elaine Whitfield Sharp, and her husband Dan, to the defence fund fighting for their daughter.

Ms Whitfield Sharp was fired by Louise Woodward, now 20, last month after allegedly telling a trooper who arrested her for drunken driving she believes the nanny is guilty of murder and is having "a hard time handling it".

She denied making the remark.

Elaine Whitfield Sharp now says a $15,400 (£9,131) bill purportedly for four months' accommodation for Sue Woodward, Louise Woodward's mother, at the Sharp home in Massachusetts during the trial last year was a fake.

The bill lists food and telephone costs, but Ms Whitfield Sharp says no money ever changed hands.

Her husband Dan said: "It is a forgery, and I would note a poor one at that.

"I don't believe we ever charged her (Sue Woodward) a dime for anything, but we certainly never charged her $15,400 for anything."

Andrew Miller, Louise Woodward's local MP in Cheshire, has confirmed that the trustees plan to hold a meeting on Tuesday.

He said: "The trustees are obliged to meet under trust law when accusations are made about impropriety.

"The allegations are false and can be proven to be false. What we are seeing ... is another twist in the continuing saga aimed at damning the Woodward family.

"It is black propaganda and needs to be killed on that basis," he added.

The family's British lawyer Paul Barrow said: "The allegations are denied, this is not a forgery."

'Hard time'

A jury convicted Louise Woodward of second degree murder of nine-month-old Matthew Eappen in February 1997 and sentenced her to life imprisonment.

A judge later reduced the verdict to manslaughter and sentenced her to the 279 days she had served in prison since her arrest.

She has to stay in Massachusetts pending the outcome of appeals by defence and prosecution against the manslaughter verdict which secured her release.
