The UK Parliament and British Government deal with all reserved matters for Northern Ireland and Scotland and all non-transferred matters for Wales, but not in general matters that have been devolved to the Northern Ireland Assembly, Scottish Parliament and National Assembly for Wales . Additionally, devolution in Northern Ireland is conditional on co-operation between the Northern Ireland Executive and the Government of Ireland (see North / South Ministerial Council) and the British Government consults with the Government of Ireland to reach agreement on some non-devolved matters for Northern Ireland (see British--Irish Intergovernmental Conference). England, comprising the majority of the population and area of the United Kingdom, remains fully the responsibility of the UK Parliament centralised in London . </P>
