Survivors of a North Sea helicopter crash which claimed four lives have won millions in compensation.

The CHC Super Puma had 18 people aboard when it plunged into the sea near Shetland in August 2013.

Both pilots and 12 passengers escaped but Sarah Darnley, Duncan Munro, George Allison, and Gary McCrossan were killed.

Nine of those survivors have now won compensation totalling between £2.5m and £3m.

A spokeswoman for law firm Digby Brown said: "Our clients were a group of people who were just going to work when their lives were changed in some of the worst ways imaginable.

"The cases were about providing them with access to legal recourse and fair compensation.

"All of those involved in the incident will have to live with its effects and repercussions for the rest of their lives.

"The most important outcome is that the settlements will hopefully allow those affected by the events of that night and their families to move on with dignity."

A report published in March by the Air Accidents Investigation Branch said the helicopter's instruments were not effectively monitored during its approach to Sumburgh Airport on August 23.

No mechanical faults which could have caused the crash were found.
