The driver of an autism school minibus involved in a motorway crash with a lorry has died.
Police said a third person died in hospital on Friday after two people died at the scene of the collision on the M4 on Thursday.
The victims, who were all in the minibus, were staff members at Prior’s Court School in Thatcham, Berkshire.
Prior’s Court chief executive Mike Robinson said the school “will never quite be the same again”.
Thames Valley Police said there have been no arrests over the crash.
Insp Andy Storey said three passengers who were also in the minibus remained in hospital and that two of them had life-threatening injuries.
He said two other people from the minibus had been discharged from hospital and along with the lorry driver, who suffered minor injuries.
