Local elections are due to be held across swathes of England in May. I am unsure about Wales, Scotland and Northern Ireland. The ruling Labour Westminster Government, whose popularity has collapsed spectacularly in the six months since they won power, and are accordingly expecting and expected to lose a great many local council seats in these local elections, are considering cancelling these elections in a number of councils, as they are "planning reorganisations of these local authorities".
Put bluntly, and perhaps simplistically, the UK relies constitutionally, on the Government "doing the right thing"; in this case facing the electorate. The suspicion is that they intend to "dodge" facing the electorate, using the excuse of future reorganisations. Can they do it? They have a massive parliamentary majority, notwithstanding the collapse in public support, and Parliament is sovereign, so yes, they can, despite it not being " the right thing".
