This is patently absurd. Labour already inherited the highest tax burden in 70 years from the Conservatives - this budget increases the tax burden by a further £40bn to fund extra spending. Government borrowing is also going to increase by an average of £32bn a year for the next five years due to this budget.
If this is what they call austerity, I’d hate to see what these people think government largesse looks like…
The goal here is that it’s famously difficult for third parties to get an appropriate measure of media attention in the UK. The newspapers are highly partisan, and the TV news interprets the ‘balance’ requirement to mean they can just give the government view and the main opposition view on every issue (unless the government and main opposition happen to agree - which is why the Lib Dems got a fair hearing in the media on Iraq in the early 2000s).
So third parties need to have a gimmick to trick the media into giving them airtime, which then allows them to talk about their issues. Charles Kennedy did it but being entertaining on chatshows and HIGNFY; Nigel Farage does it by being outrageous and offensive; and Ed Davey has worked out that he can do it through stunts.
