Kirill Dmitriev is a rare breed of Russian diplomat.

At 50 he is relatively young and he has a deep understanding of the US, having studied and worked there for several years.

He is also a man of commerce, as head of the Russian Direct Investment Fund, and a good fit for his opposite number in the Trump administration, special envoy Steve Witkoff.

Dmitriev now finds himself under the spotlight over a draft peace plan that emerged after he spent three days with Witkoff in Miami.

His team has refused to comment on its proposals, which read like a Putin wishlist, requiring Ukraine to cede territory under its control and slash the size of its military.
