Two boys killed in a Christmas Day crash were on their way to the wedding of boxer Amir Khan's cousin.
Arsalaan Habib, four, his brother Adnan, 10, and their aunt, Bushra Tazarib, 32, died on the M6.
The boys' mother Parveen, 38, who was driving, and their 17-year-old sister Misbah survived.
All five were on their way to Bolton - where the boxer lives - when the accident happened.
The bride, Rabia Khan, is the former world champion's second cousin and he was at the ceremony when the news came through, his father Shah Khan has confirmed.
Mr Khan said the family were from the groom's side and that Amir and the rest of the family were very upset to learn of the accident.
He said: "It shocked everybody. The family is trying to support them."
The boxer told The Sun today: "My heart goes out to the families of those involved in this terrible accident. No one could believe it. One minute everyone at the wedding was joyous, the next it had turned into despair."
The boys and their aunt died after the car they were travelling in crashed and overturned on the M6 near Stoke-on-Trent at about 11.25am. All three were from High Wycombe in Buckinghamshire, Staffordshire Police said.
The boys' mother - who was driving the red Ford Focus - and a female relative who was a fellow passenger were both injured and were taken to hospital. They were discharged from the University of North Staffordshire Hospital on Wednesday. A Staffordshire Police spokesman said: "Specially trained liaison officers have been appointed to support them at this incredibly difficult time for the family."
