Has devolution undermined parliamentary sovereignty?

The debate within British politics has been dominated by question of whether or not devolution has undermined parliamentary sovereignty. The meaning of this being - parliament and its elected members only have the power to pass legislation as well as end them. In 1998 a referendum was held on the devolution of Scotland, Wales and Northern Ireland, and the outcome being they all became devolved. As a result, parliament no longer interfered in the domestic affairs of each devolved bodies. For example, in Scotland the Scottish parliament pass legislation on areas such as Healthcare or Education (Scottish students do not pay university tuition).

Although parliament in Westminster did lose considerable power in domestic matters, as they are unable to amend legislations in those regions without consulting with the devolved assembly’s legislatures. It is important to understand that the Devolution Act, still, has the ability to come under the scrutiny of Westminster and be repealed. However, this act is deeply entrenched in the devolved areas, and since it was a referendum that brought about devolution, this proved that there was also a mandate for it.
