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 two other minibus passengers, who suffered life-threatening injuries, remained in hospital.
One young adult from the school remains in hospital, while two others have been discharged.
Insp Storey said the lorry driver, who suffered minor injuries, had also been discharged.
The crash happened at about 12:20 BST on the eastbound carriageway of the M4 between junction 14 at Hungerford and junction 13 at Newbury of the M4.
The westbound carriageway was initially closed to allow three air ambulances to land and the eastbound side remained closed for about nine hours.
