A hairdresser charged with the murder of EastEnders actress Sian Blake and her two children is expected to enter pleas in court later.

Arthur Simpson-Kent, 48, is accused of killing his 43-year-old girlfriend and their sons Zachary, eight, and four-year-old Amon between December 12 and December 16 last year.

The victims vanished on December 13 and their bodies were found buried in the garden of the family home in Erith, Kent, on January 5.

Simpson-Kent was arrested at Heathrow Airport in February after agreeing to his extradition from Ghana.

He is due to enter pleas to the charges when he goes before Mr Justice Singh at the Old Bailey. A trial has already been provisionally fixed for October 4 at the same court.

Sian played Frankie Pierre in 56 episodes of EastEnders between 1996 and 1997. She was suffering from motor neurone disease before she died.
