Who living has the most knighthoods?

It's difficult to say definitively who has the most knighthoods currently living, as different countries have their own systems of knighthoods and there is no central database tracking them globally.

However, we can look at some individuals known for their extensive honors:

* Prince Philip, Duke of Edinburgh (deceased 2021): He held numerous honorary knighthoods and other awards from across the Commonwealth.

* Queen Elizabeth II (deceased 2022): She was a sovereign and thus not a knight, but received many honors and decorations from other countries.

* Prince Charles, now King Charles III: He holds numerous honors, including the Order of the Garter, the Order of the Thistle, and the Order of Merit.

* Sir David Attenborough: He has been knighted in the United Kingdom and received other honorary knighthoods from countries like Australia and New Zealand.

Ultimately, the answer is complex and depends on how you define "knighthood" and what system you're looking at. It's likely that someone with extensive service in the military or public service could have a large number of awards, including knighthoods, but tracking them accurately would be a significant undertaking.
