Which Dragon's Den investor was knighted by Queen Elizabeth II in 2000?

Alan Sugar was knighted by Queen Elizabeth II in 2000.

The honour recognised Sugar's services to business. He had founded and developed Amstrad, turning it into a significant British consumer-electronics company, and had become a prominent figure in technology and entrepreneurship.

Sugar's title is often written as “Sir Alan Sugar,” reflecting the knighthood. He later became a television personality through The Apprentice and joined Dragon's Den as an investor, but those television roles occurred after the 2000 honour.

This fact is easy to confuse with other dragons who received business or charitable honours. A knighthood is specifically a British honour that permits the recipient to use “Sir” before a personal name. Sugar's baronetcy and his later appointment to the House of Lords are separate aspects of his public career.
