The wealthy Russian businessman nicknamed "Putin's chef" - Yevgeny Prigozhin - has his fingers in lots of pies.
He made his fortune running catering businesses in the 1990s - hence the nickname. And he joined President Vladimir Putin's elite circle when the Russian leader started dining at his luxury floating restaurant in St Petersburg, called New Island, in 2001.
Like many other Russian oligarchs, Mr Prigozhin, 58, has branched out into various businesses, uses shadowy offshore firms and enjoys a lavish jet-set lifestyle.
But the US government is trying to clip Mr Prigozhin's wings: it has stepped up sanctions against him and his businesses because of his alleged meddling in US elections.
Investigations by Western journalists and think tanks also link Mr Prigozhin to a Russian mercenary group called Wagner, accused of pursuing Russian state interests in war-torn Syria and Libya, as well as hotspots in sub-Saharan Africa.
