A stricken Canadian submarine has left the Faslane naval base at the start of its journey home.
The vessel carrying the Chicoutimi makes its way out of Faslane
HMCS Chicoutimi was towed to Scotland in October after a fire on board killed one crew member, Lieutenant Chris Saunders, and injured others.
The former Royal Navy vessel is making the crossing of the Atlantic on board a Norwegian transport ship.
A spokesman said: "The submarine will take around six or seven hours to get through the Clyde Estuary.
"The weather conditions were what stopped the captain from setting off earlier this week but they seem fine now."
The voyage to Halifax in Nova Scotia is expected to take a fortnight.
The Chicoutimi drifted for three days off Ireland after the fire, which broke out during the submarine's maiden voyage under the Canadian flag
Lt Saunders died after the incident on HMCS Chicoutimi
An investigation found the blaze started in the commanding officer's cabin and a smaller one started in an oxygen generator.
Canada's Prime Minister Paul Martin paid tribute to Lt Saunders, 32, a married father of two, saying he "gave his life serving his country and we owe his family our deepest condolences".
The Chicoutimi was decommissioned by the Royal Navy in the early 1990s. It was then refitted by BAE Systems before being recommissioned for service in the Canadian Navy.
The fire prompted Canadian opposition parties to accuse their government of buying "inferior submarines" on the cheap.
But UK Defence Secretary Geoff Hoon said the vessel had been brought up to Royal Navy standards.
