The partner of former Eastenders actress Sian Blake will stand trial in the autumn, accused of killing her and their two young sons.
Arthur Simpson-Kent will face trial for murder after Blake, 43, and their sons Zachary, eight, and Amon, four, were found dead at their family home.
The three victims went missing on 13 December before their bodies were found buried in the garden of their home in Erith, in south east London, on 5 January.
Simpson-Kent, 48, was arrested at Heathrow Airport last week after agreeing to be extradited from Ghana.
He appeared at the Old Bailey via video link from Wandsworth Prison on Tuesday morning.
Wearing a grey sweatshirt, Simpson-Kent spoke only to confirm his name.
No application was made for bail and he was remanded in custody.
A plea and case management hearing was fixed for 3 May ahead of a provisional trial on 4 October.
