That they consider themselves a democracy. For example, apart from her own constituency, nobody voted for May. Parliament didn't vote for BoJo. How is that democratic? Also, that when they vote, they vote for who they think might win rather than what they believe in.
As we have seen in recent weeks, lots of British people don’t understand how our Parliamentary democracy works, either.
We elect MPs to represent us in parliament. Each MP represents a constituency of about 80,000 people and the vast majority of those MPs belong to either the Conservative or Labour parties.
The public don’t elect the leaders of those parties. They are elected by the MPs and members of their party.
Prime Ministers are NOT elected. They are appointed by the Queen.
The person she appoints is almost always the leader of the largest party in Parliament. The Conservative party is currently the largest party and together with its partners the DUP currently commands the support, or ‘confidence’ of the majority of MPs, so its democratically elected leader, Boris Johnson, was appointed Prime Minister. It is not at all unusual for a new PM to be appointed without winning a General election first. John Major, Gordon Brown and Theresa May were also appointed in similar circumstances in recent decades.
If Johnson is unable to maintain the support of the majority of MPs, and loses a ‘vote of confidence’, Parliament will be dissolved, we will have a general election and a new Parliament will be elected.
