The British government confirmed that Brazil refused to let the HMS Clyde, which was on its way to the Malvinas Islands, dock in a port in Rio de Janeiro, in a clear move by newly appointed President Dilma Rousseff to show her support for the Argentine claims to the islands.
A spokesman for the Foreign Office said: "We can confirm that HMS Clyde had planned to make a routine port stop in Rio de Janeiro in early January.
"Brazil did not grant diplomatic clearance this time. We respect Brazil's right to make such a decision. We have a close relationship with Brazil.The UK-Brazil defence cooperation treaty signed last September is a good example of our current," the British spokesman added.
