Our PM is finishing tomorrow. Another PM will replace him. He or she (probably she) is being chosen by 160,000 Conservative party members not the British electorate. We might have a general election until next year or the year after. Our old PM has been found to have lied and broken laws. His popularity meant his party got an 80 seat majority in the 2019 election and are changing electoral boundaries to make it difficult to defeat them. It also seems Scottish voters may try and go for independence making it virtually impossible to get the Conservative government out of power.
I think of our PM as a Trump mini-me. He even thinks he can get back in power! The new PM will probably be Liz Truss. She does not seem to know what she is doing. It seems the rich and entitled rule. The rest suffer.
