The best friend of a teenager killed with his father in a horrific car crash has described him as a popular and hard working boy who was "always smiling".
Ethan Sarkar, 14, and his father Derek Sarkar, 46, died when their Volkswagen Golf collided head-on with a Volvo on the A614 near East Cowick, East Yorkshire, on Saturday.
The driver of the Volvo, Sheila Stavert-Lee, 70, from Wigginton, near York, was also killed in the crash, and Mr Sarkar's wife and nine-year-old daughter, who have not been named, sustained critical injuries.
The two survivors are in a serious condition at Leeds General Infirmary.
Speaking from outside the Sarkar's family home in Sheldon Heath Road, Birmingham, Connor Meredith, 14, said he had been devastated by news of Ethan's death.
He said: "He was the best. He was my best friend and I loved him, I thought the world of him."
Connor added he believed the family had been visiting relatives for a birthday celebration.
Humberside Police said Mr Sarkar was driving north over a canal bridge on the A614 with his son in the front passenger seat when their silver Volkswagen collided with Mrs Stavert-Lee's red Volvo V70.
A force spokeswoman said: "It appears the Volvo had crossed on to the wrong side of the carriageway into the path of the oncoming Golf."
The father and son were pronounced dead at the scene along with Mrs Stavert-Lee. Mr Sarkar's wife and daughter were airlifted to Leeds.
