The Foreign Office has confirmed the body found in the River Vltava in Prague is that of missing Hampshire father Karl Law.
The 35-year-old father of one was on a stag do in the capital when he went missing on 15 November.
Hopes had been raised Law would be found alive after two reported sightings of him on 16 November at the Palacky Square and the following day in the area of the National Theatre.
But the scantily clad body found by Czech police has been confirmed as Law.
"We can confirm the death of a British national who was reported missing in Prague and we are in touch with the local authorities," a Foreign Office spokesman said.
"We are in close contact with the family and are providing consular assistance at this difficult time."
A Facebook page set up to try and help find Law attracted almost 15,000 likes.
A post-mortem is due to be carried out by authorities today (8 December)
