Dasha Chernyshova, a Moscow correspondent believes Putin's condolence message to the UK was sincere and that Russians respected the Queen. Andy Mok Senior Researcher at the Centre for China and Globalization says President Xi could not make the funeral due to other geopolitical priorities but China was represented despite some tensions. And Stockwell Day, the former leader of Canada's official opposition says Justin Trudeau made an error in judgment and was not fully representative of the sombre mood in Canada.
