How do you kosher a Gherkin?

Pickles have been a Jewish culinary favourite for centuries, and now one of our number owns the most famous gherkin of them all.

Jewish-Brazilian billionaire Joseph Safra has bought the 180m-high Gherkin skyscraper in London - officially called 30 St Mary's Axe - for a reported £726 million.

Mr Safra, whose £9.4 billion fortune makes him the 46th richest person in the world, was born in Lebanon but moved to Brazil with his family when he was 12.

It was in Sao Paulo, where he still lives, that he created Banco Safra, now the country's eighth largest bank. Safra Group now controls worldwide assets worth more than £126 billion.
