Why is tony Blair one of the worst britons?

Tony Blair is often criticized as one of the worst Britons due to his role in the Iraq War, which many believe was based on misleading information about weapons of mass destruction. His decision to support the invasion led to significant loss of life, destabilization in the region, and ongoing conflict. Additionally, his government's domestic policies, including controversial reforms in healthcare and education, have also drawn criticism, further tarnishing his legacy. These factors contribute to a perception of him as a divisive figure in British history.
