In his 20s, yet running a $50billion book, Kweku Adoboli had worked his way up the trading floor at the very point the market crashed.

His actions wiped £2.7bn from the UBS share price, prompted the resignation of their chief executive - and got him a seven-year jail sentence for fraud.

In this remarkable interview with Olly, he reveals a corporate culture of ‘wilful blindness’, explains how he fell foul of the UK’s hostile environment policy for migrants - and re-lives the moment he realised that, having taken responsibility for his actions, he would forever be known as Britain’s biggest ‘rogue trader’...

Elsewhere this week, Ollie Peart highlights ‘anonymous work talk’ app Blind, and the trend for ‘baby sculpting’ in gross-out cake baking. He also reports back on his attempts at ‘neuro-priming’. If you have a challenge for Ollie to try in The Zeitgeist, drop us a line.

Meanwhile, down the Foxhole, Alix Fox sheds light on British attitudes to sex in the dark, and advises an HIV-positive listener about alternatives to penetration when his viral load hits detectable levels.
