An insight into his "vindictive streak."

Billionaire and Virgin Group founder Richard Branson published a blog post today in which he addresses a meeting he had with Republican Presidential candidate Donald Trump.

Branson reveals that some years ago, he was invited by Donald Trump to a one-to-one meeting at his apartment in Manhattan. The invitation surprised Branson as he had never met Trump before.

"Even before the starters arrived he began telling me about how he had asked a number of people for help after his latest bankruptcy and how five of them were unwilling to help," Branson wrote.

"He told me he was going to spend the rest of his life destroying these five people.

"He didn’t speak about anything else and I found it very bizarre. I told him I didn’t think it was the best way of spending his life. I said it was going to eat him up, and do more damage to him than them.

"There must be more constructive ways to spend the rest of your life (Hopefully my advice didn’t lead to him running for President!)

"I was baffled why he had invited me to lunch solely to tell me this. For a moment, I even wondered if he was going to ask me for financial help. If he had, I would have become the sixth person on his list! "

Branson then revealed how worried he is about the upcoming election and the "vindictive streak" of Donald Trump.

"I left the lunch feeling disturbed and saddened by what I’d heard. There are a lot of frightening things about this election; not least that policy has been pushed so far down the agenda.

"What concerns me most, based upon my personal experiences with Donald Trump, is his vindictive streak, which could be so dangerous if he got into the White House.

"For somebody who is running to be the leader of the free world to be so wrapped up in himself, rather than concerned with global issues, is very worrying."

But, at the moment, we're more concerned about the standard of his jokes.
