The farmer was jailed for life the following year - but his murder conviction was reduced to manslaughter on appeal and he was freed in 2003.

The eccentric bachelor died aged 80 last February, and bequeathed his farm and most of his £2.5m estate to his close friend Jacqueline Wadsley, who previously ran the Hare & Hounds pub in Wisbech.
