Police in Canada are searching for a Briton thought to have drowned in an incident on a river in which two people died.
They are believed to have been swept over a set of waterfalls on the Kettle River, near Grand Forks in British Colombia, on Saturday.
The bodies of a local couple in their 70s, who were sharing a small inflatable dinghy, were recovered from the water.
A search for the 50-year-old man, from Scotland, is continuing.
Police said it is believed they were with a party of around 13 people. Witnesses said part of the group were swept up in the current.
The Royal Canadian Mounted Police (RCMP), said: "The RCMP Southeast District helicopter and ground searchers were unable to locate the third individual... the 50-year-old man was also swept over the Cascade Falls on the Kettle River late Saturday afternoon.
"An extensive air and ground search was completed late Sunday afternoon which yielded no sign of the man. Search and rescue technicians will monitor the area in the coming days in attempts to locate the man's body.
"The family of the 50-year-old Scottish man have been advised by the RCMP and Grand Forks Victim Services personnel, that the man is presumed to have drowned."
The Foreign Office confirmed it was aware a British national was reported missing in Canada on July 29.
A spokesman said: "We stand ready to provide consular assistance."
