Timeline of the London Bridge attack

The head of the Metropolitan Police's counter-terrorism unit, Commander Dean Haydon, has released new details of how the events of the London Bridge attack unfolded.

Saturday morning - Khuram Butt tries to hire a 7.5-tonne lorry online but does not provide payment details so the rental does not go ahead.

17.47 - Butt receives a text confirming the hire of a white Renault van, using a recently activated mobile phone, for 17.50 Saturday to 10am on Sunday.

18.30 - Butt, Youssef Zaghba and Rachid Redouane drive in a red Corsa to Harold Hill, Romford, to pick up the van.

19.17 - They arrive at an address in Barking, where Zaghba lived.

19.38 - The trio leaves in the van heading into central London.
