Did the 'Distinguished global leader in residence' aka Gordon Brown get upgraded causing others to lose their paid for seats?

The Mail report a rather odd story:

'Gordon Brown sparked a mutiny on a British Airways flight after he was blamed for an attempt to downgrade a heavily pregnant woman and Red Cross doctor into more cramped seats.

The extraordinary scenes - dubbed Mutiny On The Brown-ty - unfolded on a flight from Abu Dhabi to London, when passengers lost their seats before the former Prime Minister's six-strong entourage got on board.

It prompted an angry war of words with an 'aggressive' Brown aide, and led to a formal complaint to BA and an offer of compensation described as 'derisory' by those involved.'

Read the story and the denials from Gordon Brown and British Airways and decide who you believe. For my part I doubt practically everything Britain's worst ever Prime Minister and main reason (along with Ed Balls) for the UK's dire economic position.
