It'll be like a merry-go-round. Taxes are going to be painful over the next 5 years, as are cuts to services, not the fault of whichever government had gained power, just the cost of all this Covid pandemic. Voters may then blame Boris at the ballot box, let in a politician that has a Marvellous Magic Money Tree, they'll spend money we haven't got, them we'll start all over again.
I think the government responded very well to the pandemic. That's my opinion, I know there are those that don't agree.
