He is right in a sense, if you're looking at just GDP growth then the UK under the Tory government 2010-16 was performing well against other similar economies. After the Brexit vote we went from the best performing economy in the G7 (GDP growth) to the worst. They have brought the deficit under control too, although it took them longer than the pledged. Looking at other economics markers like real wage growth etc, the UK performed very badly in the same period. The Brexit project has already cost us hundreds of billions and will continue to do so. In the absence of that I think they'd have a much better case for arguing that the are the party of fiscal responsibility. Brexit should have really killed that idea but general global prosperity since then has kept us with poor growth but not at a level where it has noticeably hurting enough of the electorate to have a real impact politically.
The deficit is just one measure used as a reason for austerity - most economists actually agree that in order to boost economic growth you need to allow the deficit to expand. The tories hid behind the deficit as a means to cut down on public spending & welfare cuts, to pay for banker bailouts.

Also it wasn't just that 'it took them longer than they pledged", that implies they simply missed a deadline. Osborne said austerity would end in 2015, the latest estimates are that it will end in 2025, that's a gross miscalculation - especially when you consider that the poorest in society are dying & being forced out of their homes because of cuts to their benefits, as a result of austerity measures.
So even by their own misguided measures, they have failed - miserably so.
That's before we even get into the fact that they have admitted to losing £2.3 billion and have nothing to show for it.
Austerity might not be "hurting enough of the electorate" but it's killing thousands of people, and just because the majority of us are in a privileged position to not have to rely on benefits & food banks, doesn't mean we should put faith in a party that hides behind dated terms of fiscal responsibility, with no recent results to show for it.
In the light of what happened in 2008 what measures do you think would have been the correct ones? How would you have addressed the deficit and what evidence to you have that it would have worked?
As I see it now we have less than 4% unemployed (that's virtual full employment by most peoples reckoning), inflation at 1.5%, Interest rates are 0.75%. The deficit is down. Wage growth is at an 11 year high at around 3.5%. Yes austerity hurt and hopefully that will now be addressed. But I would be interested in a proper summary of just how any other method would have addressed the biggest financial issue to hit the country since the Wall St crash.
The unemployment rate is pretty misleading, considering 2/3's of the recent 3 million hired are self-employed or on zero-contract hours because there's not enough jobs - so yes they have a job, but they have no stable or reliable income. This, plus an increase in state-pension age thus forcing people to work while they're much older, added on to the fact that a large amount of migrants make up for recent job hires, plus many people living longer, thus working more - you should have the comprehension that a simple 4% unemployment rate doesn't even begin to tell the whole story.

So yes, unemployment is down, but 6 million jobs pay below the 'living wage', therefore 6 million employed are classified as in poverty, and rely on foodbanks - this includes many Teachers, Nurses, Firefighters etc.
It's all well & good stating numbers, but wage growth affects the privileged, most public workers have had their wages stagnated, but CEO's, MP's, C-level executives have seen their wages double in the same time period, when you take that average of course you'll be led to believe that wages are increases - in reality, for most people they are not - not at the rate to keep up with cost of living.

Nurses, Police Officers, Teachers etc have actually seen their wages go down on average in the last 10 years when you take inflation into account.
If you don't think there are alternatives to growing an economy than austerity, then I really don't feel like revisiting my A-level economics books - these are things which are easily researchable online. My point remains that the Tory being the part of fiscal responsibility is a delusion.
Blair presided over the longest sustained period of economic growth since, what, the 1920s? Despite that, when the inevitable crash came (remember no more boom & bust?) there was nothing in the coffers to cushion the fall, leading to austerity.
No doubt you are going to bleat on about it all being the bankers fault, but it still remains that, there was an opportunity to put some money aside to cushion the inevitable bust, whoever's fault it would turn out to be, and that opportunity was not taken.
See above.
