In September last year, thousands of UK investors lost their savings after Lehman Brothers collapsed. More than 5,500 people had invested a total of £107m ($178m, €124m) in structured products. Not only had the involvement of Lehman Brothers been hidden, but many of these products had been marketed as 100 per cent protected, secured or even guaranteed.

A year on, these investors are still waiting for concrete action from the UK authorities – the kind of intervention seen in Switzerland or Hong Kong, where thousands have received financial compensation.
