The search continues today for two Britons whose sailing boat was capsized by a large wave off the coast of Portugal.
The accident happened at 3.30am yesterday while the men battled rough seas as they headed towards a marina north of Porto.
The missing men are aged 23 and 52, while a 24-year-old crew member was able to swim to safety at Povoa de Varzim.
Search teams have used a helicopter to try to find the men.
A Foreign Office spokesman said: "We are aware of a boating accident off the coast of Portugal involving three British Nationals, two of whom are missing.
"We have offered consular assistance."
The men had been sailing their yacht, Water Waves, from the north-western Spanish port of Vigo when they hit a storm.
