Traditionally it has been the constitutional power of the monarch to dissolve parliament and trigger a general election at will.
Ostensibly, the Fixed Term Parliaments Act of 2011 removed this power.
However, since parliament derives its power from delegated royal prerogative and acts can only become law with royal assent. Is this actually binding and could the Queen still dissolve parliament if she so wished, even if she had to take a few steps to repeal that law first?
