Spotlight On... Roger Jenkins; Managing partner, BTG Pactual

One half of the Jenkins brothers right?

Wrong. Try Britain's best-paid banker, reputedly making up to $75m (£47m) a year when he left his role as head of Barclays' tax-planning business in 2009.

That's a meaty old pay packet. Does that qualify as a cash mountain?

There's no official definition of a cash mountain, but I think it's safe to assume it is one. But that's old news. The new news is that Roy's now got a paper mountain to go with it. His stake in his latest venture, the Brazilian investment bank BTG Pactual, will be valued at $195m when it floats later this month.

Wow. But I'm still convinced he's one of the Jenkins brothers

Well, he does have a brother called David. But I think you're thinking of Huw Jenkins, the former UBS investment banking chief, who is also at BTG and has the same-sized stake as Roger. But I promise they're not brothers.

Tell me more about Brother Jenkins

Roger's best known for saving Barclays from the clutches of the humble taxpayer. At the height of the financial crisis in 2007 he managed to secure £7bn of cash injections from middle eastern sovereign wealth funds.

Small wonder then BTG later tapped him to raise cash from investors and to identify investment opportunities?

Yes. Finally, you've got something right.

What's the most lavish dinner Roger's ever had?

That's an easy one. He had a very lavish dinner at his Mayfair pad in aid of victims of the Darfur conflict. It was co-hosted by George Clooney and attended by Sir Michael Caine, Matt Damon, Scarlett Johansson and U2 frontman Bono Vox.

What's Roger been up to since leaving Barclays?

He set up a private-equity fund, named Elkstone Capital, to capitalise on the opportunities in Dublin presented by the financial crisis. There he met Huw Jenkins and the two got on like a house on fire. So he decided to call it a day on Elkstone and now the pair find themselves as managing partners at BTG.
