This is such a reasonable question POGS and, in my opinion, shows what a mess politicians make solving short term problems when they should be looking at the long term.
- Some areas of the United Kingdom are devolved.
- They are the Scottish Parliament, the National Assembly for Wales, the Northern Ireland Assembly and the London Assembly.
- This mean they have been granted statutory powers from the Parliament of the United Kingdom.
- These powers are carried out by the executive bodies; the Scottish Government, the Welsh Assembly, the Northern Ireland Executive and the Greater London Authority.
- Different powers have been devolved to different areas. These powers are still held by the UK government and the devolution could be repealed by the UK Government.
- As far as I understand it you could stand for election of a devolved body, i.e., a Members of the Scottish Parliament (MSPs), an Assembly Member (AM) in the Welsh Assembly, in Ireland a Member of the Legislative Assembly (MLA), or in London a London Assembly Member and also a Member of Parliament (MP) for the UK and also an Member of the European Parliament (MEP).
Devolution is different to federalism as the powers are controlled from the top - the UK Parliament "allows" the devolved areas to make decisions. If we had a federal system the UK would be divided into decision making areas - including the existing ones - and they would send MPs up to the UK Parliament taking their power to that level.
I do hope this helps and doesn't make it even less easy to understand ... [no crossed fingers emoticon]
