Bill Browder: If Putin loses Ukraine war ‘he will not stay in power’

Bill Browder is perhaps best known for being one of Vladimir Putin’s fiercest critics – but he was once one of the biggest foreign investors in Russia.

He and the Russian President fell out so badly that Putin called him a ‘threat to national security’ and denied him entry to the country.

In a new book, Mr Browder gives details of his relationship with Putin and it reads like a spy novel. We speak to him, and begin by asking him about his friend Vladamir Kara-Murza – an opponent of the Russian president who was detained upon his return to Moscow yesterday.
