'Putin's Rabbi' is Chief Rabbi Berel Lazar. Who also happens to be good friends with Nathieniel Rothschild and they all go to the WEF together. So yeah they are all linked.
"Tonight we are also honoured to be hosting the Honourable Nathaniel Rothschild, who is here with us tonight as Guest of Honour." Rothschild introduces Lazar:
Nathaniel Rothschild: "My only qualification for speaking tonight is that I am very good friends with Rabbi Lazar. I have been going to Russia since 1992, when I was still a student in Oxford. When I began visiting Russia regularly around 2001, I didn't have much idea about the resurgence of Jewish life. However, I met Rabbi Lazar in Switzerland at the World Economic Forum in Davos and I was struck by watching this figure and we eventually connected and started talking, and from there began a friendship and I started visiting his centre in Russia, many times a year....
I have only wonderful things to say and I am very honoured to introduce him here tonight."
Rabbi Lazar then talks about Putin's life.
