The government in the UK is definitely wanted there. It would be hard to find anyone, anywhere, that would say that they want it to be lawless with no government. On the other hand it is also hard to find anyone that doesn't wish for their government to be improved. That is all that is wanted in the UK, improvement of their government. They do not wish for it to actually go away.
The UK government, like the US government, is widely unpopular. The people of the UK really need to elect new parties and people to replace their old aging institutions and parties. The UK and US governments suck because the people suck there. They need to take charge of their governments again.
