The fact that they were elected as a 'change' government and have barely done anything that really faces up to the scale of the challenge the country faces? If you're below the age of about 55, then the budget did absolutely nothing for you except put taxes up, and not even to improve services.

I appreciate things time but so far the government have enormously walked back their planning reform proposals, which was one of their few pro-growth policies, and haven't really made any dent in anything else substantive. It's been pretty clear since even before the election that they didn't really have a plan, and they got a fairly light scrutiny through the campaign because the Tories were so appalling. Then since they got in they're just scrambling around looking fairly incompetent and the dearth of talent on the cabinet has been pretty plain to see as well. Largely I want Labour to succeed but they're not making it easy to like them.

This is politics so attacks will always follow blunders on either side.

In this case this is an extremely unpopular government to start with that increases taxes across the board while handing out more benefits and claiming that they had no choice because of the state of the public finances, and we learn that they possibly misled the public on that latter point. So, yes, in politics and especially British politics this means a riot against the Chancellor (who was also caught recently having let her house without the required legal licence, btw, after the [now former] Deputy PM was caught dodging taxes on the purchase of a second home...) because everyone "smells blood" but that's the game and it's not completely undeserved, either.

Money.

They were elected with 33% of the vote thanks to our FPTP system, the lowest in history. They were unpopular when they were elected and have done nothing to change that.
