The boss of Heathrow Airport has apologised to the over 200,000 passengers whose journeys were disrupted by its closure last month following a fire. Thomas Woldbye offered his "deepest regrets" adding that the "situation was unprecedented". Speaking to MPs, he said he recognised "the considerable inconvenience and concern it caused".

UK MPs have been grilling company representatives involved in the response to a Heathrow Airport power outage that saw flight operations grind to a standstill.

The official said he had raised concerns about Heathrow’s electricity supply days before a power outage forced it to shut down. Heathrow disputed the relevance of the official’s comments.
