The UK's spy chief says Putin invited Wagner boss Prigozhin 'for tea' — and admits even he is baffled by the Russian leader's behavior

• Vladimir Putin had tea with mutiny leader Yevgeny Prigozhin, the UK's spy chief said. 
• Richard Moore said the Russian leader's actions after the mutiny were "mysterious."
• The June uprising was the most serious threat to Putin's power in decades.  

Wagner chief Yevgeny Prigozhin is "floating around" and recently went for tea with Russian President Vladimir Putin, according to the chief of the UK's MI6 spy agency. 

Speaking at an event in Prague in the Czech Republic, MI6 boss Sir Richard Moore discussed events in Russia since the failed June 23 uprising, when a rebellion by the Wagner Group saw mercenary fighters headed to Moscow.
