Not the electoral puff, but what the next government will deliver?
Unless there is a significant upturn in the economy (factors almost entirely out of any government's control) the successor will inherit the same debt, fiscal squeeze and tough choices.
If they come in on a platform of reduced taxes, that will impact directly on public services.
After they have sacked police commissioners, stopped unpopular "woke" stuff, and a whole draft of other populist savings that got them voted in, that will not even come close to covering the increased pension, health and care costs of our irreversibly ageing population.
They are the real costs that must be cut to pay for the tax reduction but will not be as the recipients of that largesse are the ones who did the voting in. Thus...
New broom, same sweep.
