Four of the victims of a crash on the M25 in Surrey that killed five members of a stag party and a recovery vehicle driver have been identified.
Tributes have been paid to Chris Janaway and Jon Chandler
Christopher Janaway, 28, Jon Chandler, 26, Andrew Graney, 29, and Matthew O'Donnell, 30, all died on their way home to Brighton, East Sussex.
They were in a rescue truck which crashed with an HGV on Monday morning.
One other stag party member and the driver have yet to be identified. A sixth passenger remains in hospital.
The men were part of a 13-strong stag party returning to Brighton from Leicestershire.
Their minibus broke down on the M1, and seven of the group, including the bridegroom, were taken home safely in a people carrier after they called for breakdown assistance.
The other six were picked up in a Dunchurch Motors Ltd recovery vehicle, which also carried the minibus.
It crashed on the M25 between junctions nine and eight, Leatherhead and Reigate, at about 0215 BST on Monday.
Mr Janaway was the first of the victims to be named by Surrey Police on Tuesday.
A statement released by his family said: "We are devastated by the loss of a wonderful son, brother and great friend."
He was in his second year working as a qualified doctor.
Colleagues at the Royal Sussex County Hospital in Brighton described him as a "very bright and well-liked doctor".
Mr O'Donnell was also said to have worked as a doctor.
Mr Chandler's sister, Emma, issued a statement paying tribute to him.

She said: "He was a much loved son, brother, boyfriend and friend, and will be missed every day.
"Having spent a great weekend with friends in Leicestershire, he was looking forward to fulfilling his role as best man at his friend's wedding, which he had been directing a lot of time, passion and enthusiasm into over the past few months."
Mr Chandler was a singer and guitarist with Brighton-based band The Mojo Fins, who had been together for four years and were due to release their debut single.
His bandmates paid tribute to an "exceptionally talented songwriter and a gifted performer".
As well as five members of the stag party, the 46-year-old male driver of the rescue truck, who was from Rugby in Warwickshire, also died.
One man suffered a broken leg and facial injuries. He was described as being in a stable condition in hospital on Tuesday.
The lorry driver involved in the collision was uninjured.
