The stamp duty cut is a bit bonkers, imo - because it leads to inflated prices.
The 45% cut is neither here nor there. A bad look for very little gain. Ditto the bankers bonus limit; I don't think the cap ever changed behaviour so removing it won't either, but the PR on it is shocking.
The 1% off income tax & NI cut is good for most, but not all. Care should have been given to those who don't benefit from this. Pensioners likely to be fine via the triple lock but other benefit receivers need further assistance - this could have been achieved via extra help on energy bills, for example. UC is already a disaster so messing with that further is wrong, imo.
Am amazed they havent touched the 40% tax threshold. Not least, because I think that would have been the thing to swing votes back to Tory. It appeals to their typical base and is likely to give those people significant benefit that they will then be reluctant to let go of.
Tax free shopping for tourists - OK.
Freezing alchohol duties seems like it's specifically aimed at bribing Scotland. I don't suppose they will fall for it 
Low tax investment zones and the subsequent bonfire of worker's rights etc that go along with that = a bloody crime.
