The Business On: Roger Jenkins, Managing Partner, BTG Pactual

So Britain's best-paid banker has joined the boys from Brazil?

Spot on. Roger Jenkins has joined Brazil's biggest investment bank BTG Pactual as managing partner. His job is to raise cash from investors and identify investment opportunities.

Remind me what he used to do?

Mr Jenkins is best known for jointly brokering a £7bn fund-raising for Barclays from Middle Eastern investors at the height of the financial crisis. The bank was thus able to avoid calling on the UK taxpayer.

A good move for BTG?

Oh yes. The sovereign wealth funds that coughed up for Barclays made a mint from their stakes as the banking sector recovered. With Latin America the hot investment story of the day, if Mr Jenkins heads to the Gulf looking for funds on behalf of his new employer, he'll be warmly welcomed.

What's he been doing since leaving Barclays?

You mean other than enjoying his house overlooking Malibu beach and jetting around the world living the high life? He had formed a boutique finance house, Elkstone Capital, to capitalise on opportunities in Dublin created by the financial crisis. It's largely been wound up.

What's he like?

He rarely gives interviews and says he guards his privacy. But he did make the headlines for hosting a lavish dinner at his Mayfair pad in aid of victims of the Darfur conflict. It was co-hosted by the similarly shy and retiring George Clooney, with a host of A-listers (Matt Damon, Sir Michael Caine, Scarlett Johansson, Bono) on the guest list. He's a former sprinter, although not to the level of brother David, who won a silver medal in the 4x400m relay at the 1972 Olympics.

And worth a bit presumably?

Mr Jenkins' package at Barclays was rumoured to be worth £30m-£70m. Still, he says he's very down to earth – he's recently separated from his Bosnian wife but when they were together, the couple liked nothing more than a quiet night in eating lamb and pasta with pal Sheikh Hamad bin Jassim bin Jabor al-Thani, the Qatari prince.
