- Rishi Sunak.

In the years since Margaret's son Justin became prime minister of Canada, rumormongers have insinuated that Justin's biological father was Fidel Castro. It is true that Margaret visited Cuba in 1976, and she has danced around the nature of her friendship with the Cuban leader. Given that Justin born in 1971 and Margaret visited Cuba in 1976, however, it is chronologically impossible for Castro to be Justin Trudeau's father. Alas, conspiracy theorists rarely take "chronologically impossible" for an definitive answer.
