UK Parliament /government = England Parliament/government, does that mean in practice England get "better conditions" than other 3 countries in UK? The Parliament/government works more in favor of England?

No the opposite. UK parliament = UK parliament. There is no England Parliament. In practice tax money flows from England to the other countries.

Yes there is not England parliament, but Scotland, Wales and NI have own parliament, so that mean England has/is UK parliament?

It does mean that some responsiblities of the Scottish Parliament in Scotland (etc) are held by the UK parliament in England.

So, for example, The UK parliament might decide to spend more money on education in England. While the Scottish parliament decided to spend less on education in Scotland. On the other hand the Army funded by the UK government in both Scotland and England.

England contribute/fill more to budget so has more money to spend comepare to others 3 countries?

Yes, in general the south east part of the UK is the most wealthy. But there is a lot of local variation.

But Commonwealth countries don't fill UK budget ? in any way?

Of course not. Can I ask, where do you live? What country? I am surprised at your questions. They seem to indicate some deep misunderstanding about the relationship of England to Scotland, and the relationship of the UK to other countries. Perhaps this is because of your experience. So please tell me more about the budget where you live.

@JamesK I am Czech, Czech republic is in EU but my nationality in my passport is not "European"...

@JamesK Who in UK consider himself British? nobody ? my impression that maybe only people from England consider himself the most as British? Will Scot offended if you call him Brit?

So does the Czech republic fill the Slovak budget? Of course it doesn't, Slovakia is independent. Now the situation in the UK is a little like the situation in Czechoslovakia before 1948. The regions of Bohemia, Moravia etc were separate regions within Czechoslovakia. People might consider themselves both Czech and Moravian, (identity is complex)

The central czechoslovak government would have overall budget responsibility, but individual regions would have local responsibility.

The situation in the UK isn't exactly the same, but it is quite close.

I am both English and British, and European. And a Sussexite and a so on. Identity is complex

It is complex in Scotland too. About 20% identify as "both Scottish and British" and a further 10% identify as "only British".

So the UK parliament is responsible for Defence, the constitution, international relations. and Strategic matters that affect the whole UK It is also responsible for things like Education in England, Transport in England. and so on. The Scottish parliament is responsible for Education in Scotland, Transport in Scotland etc.

So national component is strong at each country, then is it expected soon UK disintegration, especially after Brexit ruin economy? Is King responsible for army?

Yes, it is strong. But distintigation is not expected. It is possible, but not likely in the short term.

The king is a ceremonial leader. He has no real power.

How about in Czech? Do people still identify as "Bohemian" or "Moravian"?

Do people have different accent in Bohmia or Moravia?

But Brexit destroys UK economy and Scotland want stay in EU, this is big problem...

Scotland can't "stay in EU" because it left five years ago.

Some people want to rejoin (I want to rejoin) but so what? I can't because democracy

Constitutional matters are not a matter for the Scottish parliament

Some people in Czech want to leave EU. They can't, for the same reason.

So I hope this is clear now. The different countries in the UK are like Bohemia and Moravia used to be. They not independent, but have some responsibilities for their own affairs. They are part of the UK by choice.

But Scotland voted to stay in EU,isnt it? Brexit has big impact on economy. After people saw what happend with UK, nobody even talk about leave EU...

I don't know what you think happened. The impact on the economy was marginal The main impact was at borders since there were queues. But the actual economy didn't change much. The UK is still a rich country.

I Know waht you mean by "Scotland voted to stay in EU". But the vote was a UK vote. And the decision was taken by the UK. It wasn't a separate vote in Scotland

But this is all now ancient history.

Politics has moved on.

If I want buy car from UK, now I must pay tax because you are not in EU, because of this exports suffer..This is just one example..

On the other hand that means that the UK gets more money. That is good for the economy.

Again I say, the economy is not destroyed. the UK remains a rich country.

No your view is wrong, because of this I will not buy car....very simple mathematics

The UK doesn't make many cars anymore

And didn't before brexit. so what.

If the economy was destroyed then people would be poor. But people are not poor.

bye now

I like UK cars but I read that car industry collapse in 1970s..

Ironically, the UK joined eu in 1973. So joining EU didn't help car industry very much!

But do you now understand the relationship between Scotalnd, ENgland and the UK. This has nothing to do with the EU
