The ex-wife of missing Hertfordshire farmer William 'Bill' Taylor has been charged with conspiracy to murder him.
Angela Taylor, aged 52, of Charlton Road, Hitchin, has been charged with conspiracy to murder in connection with the disappearance of Mr Taylor from Gosmore in North Hertfordshire.
Paul Cannon, aged 53, of Pirton Road, Hitchin, has also been charged.
They remain in police custody at this time and are due to appear at Hatfield Remand Court on Saturday (1 December).
An 18 year old man and a 23 year old man, both from Hitchin, who were arrested on suspicion of conspiracy to murder have been released on police bail, while enquiries continue.
All four were arrested by police officers earlier this week.
Farmer William Taylor was last seen at his home in Gosmore on Sunday, June 3 at around 9pm –shortly before his 70th birthday.
He was reported missing to police the following day (Monday, June 4).
Since then extensive enquiries and searches have been carried out in the effort to locate him before information led officers to launch a murder investigation.
Police scoured an area within a 1.7km (1.05 mile) radius of William Taylor's farm in July.
Mr Taylor's body has not yet been found and enquiries are on-going.
