M6 crash: Tributes to brothers and aunt
Tributes have been paid to two brothers and their aunt who died in an accident on the M6 in Staffordshire on Christmas Day.
The family of Adnan Habib, 10, and Mohammed Arsalaan Habib, four, described them as "precious jewels, spreading joy wherever they went".
Their aunt, Bushra Tazarib, 32, was described as "beloved".
The boys' mother, Parveen, 38, who was driving, and their sister Misbah, 17, have been discharged from hospital.
All five from High Wycombe, Buckinghamshire, were travelling to a family wedding in Greater Manchester.
They were relatives of the groom, who was marrying boxer Amir Khan's cousin, Rabia Khan, in Bolton, Mr Khan's father said.
Their car overturned in a northbound lane between junctions 14, near Stafford, and 15, near Stoke-on-Trent, at about 11:25 GMT.'Bringing smiles'
In a statement, the family said: "Christmas Day began with all the joy all over the UK. We, as the rest of the nation, had the build-up to the Christmas holidays, attending school plays and preparing for a family wedding.
"The joy turned into tragedy in a split second, when we lost our boys moments apart and our beloved auntie."
The family described the boys as "happy and joyous" children who were "always smiling and bringing smiles to everyone they met".
The statement said Bushra Tazarib had been part of the family by marriage for almost 14 years, adding that she "was always helping and supporting every member at all times".
Insp Mark Watkins from the Regional Collision Investigations Unit said police were still in the early stages of their investigation and wanted to hear from any witnesses.
He said: "The officers are looking at CCTV and taking statements from other drivers who stopped on the day - we go back and see them two days after to give them a bit of time to get it straight in their heads because it can be traumatic for all involved."
Inquests into the deaths will be opened on Friday morning at North Staffordshire Coroner's Court.
