Arthur Simpson-Kent, Blake's former partner, was arrested at London's Heathrow Airport on Friday (12Feb16) after being extradited from Ghana to the U.K.

He has since been charged with murdering Sian and her two boys, Zachary Bilal Kent-Blake, eight, and four-year-old Amon Ben George Kent-Blake. Their bodies were found buried in the garden of the family's home in Kent, England, last month (Jan16).

Simpson-Kent is due to appear at Westminster Magistrates' Court in London later on Friday.

Blake, who suffered from motor neurone disease, had a lengthy role in hit BBC soap opera EastEnders in the mid-1990s, and she also had stints in medical dramas Casualty and Doctors, and police show The Bill.
