BOJOKER CAN'T DO WHATEVER HE LIKES!
Bojoker thinking "God help me!"
This whole mess was caused by the total lack of a Constitution in Britain or the UK. Let me make it crystal clear that a Constitution is a single document that descrives a political system and how it's supposed to work. It covers all situations that are ever likely to occur.
Parliament has actually written a Constitution which describes how "The Westminster System" of government is supposed to work. The only problem with this is that it was designed to create and govern a countr called Canada! It's called "The British North America Act 1867", which you can read here
From what I can make out, The British North America Act 1867 prevents this kind of mess by specifying that there must be at least one Parliamentary session per year, and that The Governor General (The Monarch's representative) can dissolve Parliament.
Apart from this, Parliament wrote a draft Constitution under the Coalition Government of 2010-2015, but this is only a draft with various alternatives left in the document. You can read it here
