What powers does the Queen of Britain have theoretically?

Answer 1

Great Britain has no codified constitution. There are only laws that state what the sovereign isn't allowed to do. The English Bill of Rights says that;

• The Sovereign isn't allowed to tax citizens by Royal Prerogative.1
• The Sovereign isn't allowed to interfere with the rights of their peoples to hold arms.
• The Sovereign cannot create new courts or give Judgements.2
• The Sovereign cannot interfere with fair elections.3

So, theoretically, the Queen can do anything else within them limits.

Government sources state that the Queens powers include:

• The Power to Appoint or Dismiss of a Prime Minister
• The Power to Appoint or Dismiss of other Ministers
• The Power to Summon, Prorogue, and Dismiss the Parliament
• The Power to Grant or Refuse Royal Assent to bills4
• The Power to Commission Officers in the Armed Forces
• The Power to Appoint or Dismiss members of the Queens Council5
• The Power to Command the Armed Forces
• The Power to Grant Honours
• The Power to create Corporations via Royal Charter
• The Power to issue or withdraw passports
• The Power to Declare War and Peace
• The Power to recognize states
• The Power to deploy her Armed Forces abroad
• The Power to receive, accredit and expel diplomats

The British Monarch has its place in all parts of the Political System of the United Kingdom.

The Executive - The Queen-in-Council6

The Legislative - The Queen-In-Parliament Under God7

The Judiciary - The Queen-on-the-Bench8
