If Salic Law had applied in Great Britain and Victoria had not succeeded King William IV as Queen in 1837, who would be the sovereign today?
If Salic Law had prevailed at the time of the death of King William IV (r. 1830-1837), and all births, marriages, and deaths had taken place exactly the way they did since, HRH Prince Ernst August of Hanover (b. 1954) would be sovereign today. In other words, Queen Victoria would have remained Princess Victoria of Kent (her father was Prince Edward, Duke of Kent) and the succession would have gone to her paternal uncle Prince Ernest Augustus of Great Britain (1771-1851). (He became King of Hanover in 1837.) The reason that HRH Prince Ernst August would be sovereign today is because he is the senior male lineal descendant of Prince Ernest Augustus who died in 1851.
