UPDATE: Man charged with murder of great-grandfather Don Lock in court

Matthew Daley, 34, is accused of fatally knifing 79-year-old retired solicitor Donald Lock after their cars were involved in an alleged minor shunt.

Mr Lock, who had recently been given the all-clear from prostate cancer, was driving back from a cycling meeting when he was repeatedly stabbed on the A24 at Findon, near Worthing, on July 16.

Daley was charged by Sussex Police with two offences in connection with the incident - murder and possession of a knife in a public place.

In the days that followed, relatives spoke of their sadness at the death of Mr Lock, who was due to become a great-grandfather for the sixth time later this year.

Son Andrew said Mr Lock - who had been married to wife Maureen for 55 years - was "full of wisdom, full of wit, always calm".

A keen traveller, he had been looking forward to going on a cruise with his wife before heading to Scotland for a holiday.

Dressed in a black and white striped shirt, Daley, of St Elmo Road, Worthing, appeared at the Old Bailey via videolink from Belmarsh prison and spoke only to confirm his name, shuffling in his seat throughout the brief hearing.

The case has been listed for mention in the week of October 26, with a plea hearing listed for October 30.

A provisional trial date has been set for November 16, and is due to take place at Lewes Crown Court before Mr Justice Sweeney.

As well as his wife and son, Mr Lock, a Brighton and Hove Albion season ticket holder, left behind daughter Sandra, four grandchildren and five great-grandchildren.

On the day of his funeral, at least 200 cyclists accompanied the hearse carrying Mr Lock's coffin as more than 2,000 people lined the streets of Worthing.

Cyclists formed lines at the entrance to the chapel and created an arch with their front wheels through which the wicker coffin was carried.

Mrs Lock remembered him as a "wonderful, kind, loving, generous husband" who was always supportive and always had a welcoming smile.
