Walking out of his pebbledash house with his jacket over one arm, this man cuts a perfectly unremarkable figure.

In fact, he is Hasnat Khan, the surgeon who stole Princess Diana’s heart almost two decades ago – and could have been her second husband.

Nicknamed ‘Mr Wonderful’ by Diana, he was photographed yesterday ahead of the premiere tonight of a film which chronicles their two-year affair.

Friends say Diana wanted to marry dashing heart surgeon Mr Khan.

But their relationship ended in 1997, only a few weeks before her death.

Now 54, Mr Khan lives in East London and is based at Basildon University Hospital in Essex.

He was dressed casually as he left the house yesterday, in jeans and trainers, but was carrying a suit jacket.

It was a mundane scene far removed from the dashing young heart surgeon of the film - and what might have been.

Mr Khan has vowed he will never see the film, which he said was ‘completely wrong’ and based on ‘cruel lies’.

After seeing a poster for the movie, called Diana, he said: ‘I could tell immediately those were never our mannerisms at all.

'You could just tell from that picture that it is all just presumed about how we would behave with each other, and they have got it completely wrong.

‘There wasn’t any hierarchy in our relationship. She wasn’t a princess and I wasn’t a doctor.

‘We were friends, and normal people stand like friends with each other.’

The film makers tried repeatedly to win Dr Khan’s cooperation and support for the movie, but he said: ‘I haven’t spoken to anyone involved in that movie. I have never given my approval for it.’

He said he could not imagine what the film was based on, given that he had never told anyone, not even close friends, details of his closeness to Diana.

Mr Khan, who is single after an arranged marriage ended in divorce, made the comments in the Mail on Sunday.

He added: ‘There are a hundred could-have-beens.

‘She [Diana] could be living very happily and married and having more kids, with me or with someone else.

‘It could have led in that direction. I try not to think about these things. I can’t change anything now.’
