Putin is angry at Theresa May's cold greeting: Even at the meeting she was very tough.

Tensions between the two countries have deepened since double Russian agent Sergei Scripal was poisoned, along with his daughter at the United Kingdom Salisbury on March 4th, 2018, Reuters writes.

Putin has met with May at the G20 summit in Osaka, and this one has asked Moscow to hand over Russian suspects to poison the double agent.

While Moscow has repeatedly denied being involved.

She expressed her positions in a very harsh manner. Still, meeting him was a small step, but in the right direction. I'm convinced that we need to restore our relations to a larger scale of”, Putin said.
