Mr Knowles was driving his white Mercedes northbound on the M25 near Beaconsfield when his car collided with a DAF lorry at 3.30am.

Ambulance crews and paramedics attended the accident but the 26-year-old was pronounced dead at the scene. The 53-year-old sole occupant of the lorry was unharmed.

Eric Knowles, Seb's father, is an expert on the BBC's Antiques Roadshow.

Seb Knowles lived in Reading and worked as a DJ, holding a weekly radio slot on Time FM before moving onto Wycombe Sound in 2013.

The National Association of Disk Jockeys wrote on Facebook: "All of us would like to send our deepest condolences to the family and friends of Seb Knowles (DJ Sparky B) who tragically died earlier today [Friday]. It's always a tragedy when someone is taken so young. He was a talented DJ who will be missed by all who knew him."

He was Wycombe Wanderers supporter and fans at the club held a minutes applause in his memory before their game against Northampton Town yesterday.

Friends and colleagues have taken to twitter to praise the talented young man.
