Key events and modern examples concerning devolution include the Scottish devolution referendum of 1997, Welsh devolution referendum of 1997 and the 1998 Belfast Agreement (Good Friday Agreement). All of these events have ensured that three of the four constituent countries now, to a certain extent, have autonomy. However, there is still the question of England, which, unlike Scotland, Wales, and Northern Ireland, does not have its own legislative body and is governed by the Parliament of the United Kingdom. This has caused for critics to bring up the English question, which concerns whether non-English Members of the House of Commons should be able to vote on matters concerning only England.
