The British Air Accident Investigation Branch (AAIB) on Monday confirmed it had worked with British satellite company Inmarsat to provide information that helped Malaysian authorities confirm that missing Malaysian Airways flight MH370 had ended in the southern Indian Ocean.

Malaysian Prime Minister Najib Razak earlier on Monday said that information from AAIB and Inmarsat confirmed that MH370 flew to a remote part of the Indian Ocean and ended there.

The satellite company Inmarsat, which has its headquarters in London, was appointed as technical adviser to the AAIB in the days after MH370 went missing.

The AAIB is part of the British government's Department for Transport (DfT) and is responsible for the investigation of civil aircraft accidents and serious incidents within Britain.

A company spokeswoman told Xinhua, "If they see anything that has British engineering then we assist in it. This is not something new, this is standard procedure."

The spokesman added, "As set out by the Malaysian prime minister today, we have been working with the UK company Inmarsat, using satellite data to determine the area on which to focus the search. We are not able to comment further on this investigation, which is being led by the Malaysian authorities."
