Neighbours said the couple, who have not been officially identified, both worked in the catering trade, were saving up to get married and return to their home country to teach English.
Initially police believed that a number of people had died in the blaze, but only two bodies were found after a search of the gutted premises. Two other people who lived in the flat were both away.
The cause of the fire has not yet been established and post-mortem examinations of the bodies are not due until later today.
Scotland Yard said that although the fire was initially thought to be of suspicious origin, it was now believed to have been caused accidentally.Reuse content
