LONDON, July 21 (Reuters) - London's High Court will on

Tuesday give its long-awaited ruling on how much Hewlett Packard ( HPE )

is owed over its acquisition of British software firm Autonomy

by the estate of its late co-founder Mike Lynch and his former

business partner.

HP sued Lynch - who died last August when his luxury yacht

sank off the coast of Sicily - and Autonomy's former chief

financial officer, Sushovan Hussain, in 2015.

The U.S. technology giant previously said that it planned to

"follow the proceedings through to their conclusion", meaning

HP's case would proceed against Lynch's estate.

HP had accused Lynch and Hussain of masterminding an

elaborate fraud to inflate the value of Autonomy, which HP

bought for $11.1 billion in 2011.

The deal spectacularly unravelled, with HP writing down

Autonomy's value by $8.8 billion within a year before it brought

a $5 billion lawsuit against Lynch and Hussain in London.

A judge at the High Court ruled in HP's favour in 2022,

though there have been long delays since in determining what

damages should be awarded to HP.

Lynch, once hailed as Britain's answer to Bill Gates, had

always maintained his innocence and blamed HP for failing to

integrate Autonomy into the company.

He was acquitted of criminal charges over the deal in the

U.S. and had intended to appeal the High Court's 2022 ruling, a

process which has been on hold pending a decision on damages.

Lynch, 59, his daughter Hannah, 18, an onboard cook and four

guests - Morgan Stanley International Chairman Jonathan Bloomer,

his wife Judith, lawyer Chris Morvillo and his wife Neda - died

after Lynch's superyacht Bayesian sank last year.
