British-American owned cruise firm P&O has announced it will not be stopping at three Argentine ports due to the continuing row over the Falkland Islands.
"As a British cruise company we cannot allow ourselves to be the subject of any political dispute or put our customers and crew into any situation where their enjoyment may be compromised," said a spokesman for the company.
"With this in mind, we have had to take the difficult decision to remove all Argentinian ports of call from the itinerary."
Its Arcadia and Adonia vessels will now not dock in Buenos Aires, Puerto Madryn or Ushuaia during their round-the-world cruises.
Argentinian port officials have previously turned away liners that have been to the Falklands.
President Cristina Kirchner said earlier this month that Argentina was forcibly stripped of the Falklands by Britain in "a blatant exercise of 19th-century colonialism" and demanded they be handed over to Argentina.
British Prime Minister David Cameron replied that the 3000 residents of the Falklands had a strong desire to remain British and would have a chance to express their views in a referendum on their political status to be held in March.
The islanders are expected to vote strongly in favour of continued union with Britain.
Argentina invaded the Falklands in 1982, prompting Britain's then prime minister Margaret Thatcher to send a naval taskforce to successfully reclaim the islands in a war that claimed the lives of 255 British and 649 Argentinian soldiers.
British defence officials have prepared plans for dealing with aggressive action by Argentina towards the disputed islands, according to a report on the Sunday Telegraph website.
A senior defence source told the paper: "Britain needs to be in a situation to respond very quickly to a whole series of threats - that is why we have contingency plans. Our posture has not changed but neither are we complacent."
