The partner of former EastEnders actor Sian Blake – who was found dead with her two sons – has been charged with their murder.
Arthur Simpson-Kent, 51, was arrested on suspicion of murder at Heathrow Airport after arriving in the UK on a flight from Ghana on Friday morning.
He was taken into custody at a west London police station and is due to appear at Westminster magistrates' court on Friday afternoon, Scotland Yard confirmed.
Blake, 43, and her two children, Zachary and Amon, aged 8 and 4 respectively, were reported missing on 16 December.
Their bodies were discovered on 5 January in the garden of the family's home in southeast London. All three had died as a result of head and neck injuries, a postmortem revealed.
Blake and her two children were last seen visiting family in Leyton, east London, on 13 December.

Blake, who suffered from motor neurone disease, was said by neighbours to have looked "very frail" before her disappearance.
Police officers had spoken to Simpson-Kent at the family home in Pembroke Road, Erith, but had not seen him since.
The family were reported missing on 16 December.
Blake's silver-beige Renault Scenic was found in Calvert Avenue in Bethnal Green, east London, on Sunday 3 January. Police do not know who parked it there.
Authorities believe Simpson-Kent left the UK and arrived in Ghana on 19 December.
Ghanaian police officers arrested him on 9 January on behalf of Scotland Yard and he was taken to the capital, Accra.
He was found near a beach resort in Busua and had been cutting open a coconut when armed police surrounded him, the BBC reported.
It took officers three weeks after the missing person inquiry was launched to find the bodies of Blake and her two children in the family's garden.
The Met's handling of the case has been referred to the Independent Police Complaints Commission.
