Four bankers convicted of helping Putin's friend

Four bankers who allowed a friend of Russian President Vladimir Putin to deposit huge sums in Swiss banks have been found guilty of lacking due diligence.

The former executives at the Zurich branch of Russia's Gazprombank were given seven-month suspended sentences for helping musician Sergei Roldugin, nicknamed "Putin's wallet".

Mr Roldugin reportedly paid in around $30m (£24m) between 2014 and 2016.

He gave no credible explanation of where the money had come from.
