ELI5: What are the roles/duties of Queen Elizabeth II? Does she possess any real political power? Is her position mainly honorary in nature?

She gives Royal Assent to any laws passed by Parliament (as do the Governors General elsewhere in the Commonwealth, such as Canada). No bill passed by Parliament actually becomes a law until she signs it. That said, her signature is basically guaranteed; she isn't likely to usurp the authority of Parliament.

Her non-political position also gives her the opportunity to be an observer with long institutional memory. She's been Queen for more than 60 years... her coronation was during Winston Churchill's time as PM! This does let her give advice to the Prime Minister of the day, as she may have a better grasp of historical context than he does.
