I don& #39;t think the actual levels of public spending Labour is pledging are politically costly - if you& #39;re *that* bothered by public borrowing and deficits, you probably didn& #39;t vote Labour in 2017 and probably won& #39;t now.

I think the political danger is in taxation. 1/
Labour remains committed (correct me if I& #39;m wrong) to balancing day-to-day spending over five years. That excludes their mammoth capital investment programme. But it includes spending increases on the NHS, & #39;National Education Service& #39; etc.

Those books will need balancing.

That suggests tax rises. But Labour previously pledged to protect earners under £80k from income tax rises, and is likely to stick to that.

In 2017 Lab went big on income tax rises above £80k, corporation tax rises, and some low hanging fruit reversing Tory tax cuts (eg IHT) 3/
The costings weren& #39;t accurate but they weren& #39;t totally fantastical either.

But now there& #39;ll be extra pledges - on welfare, NHS, education, social care. Those need funding. How? 4/
One route is to simply factor in the benefits of higher spending - e.g. higher spending on care delivers savings for the NHS. This is logical but also risky (the Tories& #39; SEND reforms were meant to be self-financing on this basis... HA!).

There might be some of this 5/
The other route is more transformational tax reform. And this is where the risks are. A floated Land Value Tax in 2017 nearly sunk their campaign. This has now been pared back to commercial property - but what effect will that have on local govt landlords? Has this been asked? 6/
What else might they go for? A lifetime gift tax to replace IHT is the sort of think tank policy that is logical but liable to anger voters. Equalising dividends tax with income tax makes a *lot* of sense but could hit the self-employed. 7/
We& #39;ll see what& #39;s in the manifesto, but look out for big tax reforms - proposals that make sense in think tank reports but don& #39;t translate well to an election campaign drenched with facebook ads.

It only takes one line in a manifesto to bring down a campaign /end
PS - I don& #39;t know how much it will matter whether the IFS and others say Lab& #39;s figures add up or not. Voters don& #39;t pay that much attention to the details - but if ppl think it& #39;s all unaffordable, they& #39;ll doubt your ability to deliver, reducing the electoral benefit of the pledges
