James Austin writes on Facebook: 

Who can afford private homes? Only those who are lucky to have a liveable wage and there's few and far that are in that position. It would be better spent on social housing where the need is greatest

Phil Knaggs, Chertsey, emails: 

A year ago Cameron promised 100,000 new homes. In the run up to the election it was up to 200,000 now Osborne's going for 400,000.  How many of the initial 100k have been built? All the promises seem to be by 2020. There's a lot of cramming going to be needed in the final year of this Parliament.

Simon Hopkins, Tewkesbury, emails:

Subsidising builders is the wrong approach. The real problem is our broken internal economy and shortage of supply.  We need to enable decent living wages by restoring local economies, cutting excessive centralisation and improving the balance of wealth across communities.

Paul Johnson, of the Institute for Fiscal Studies, says the chancellor has used extra tax receipts to "significantly reduce the overall level of cuts". This makes such a difference because it applies to "a relatively small part of public spending" given the amount of protected areas, he says.

Asked by a Conservative MP what has been achieved by the Northern Powerhouse, George Osborne says there is a "massive commitment" to devolve powers across transport, cultural and science institutions.

The announcement of no cuts to the police service budget has been welcomed by Paddy Tipping, chair of the Association of Police and Crime Commissioners finance group:

Personal finance expert Annie Shaw says we already knew about the rise in the state pension because of the government's so-called "triple lock". The  the new flat rate pension will be £155.65, she says. Read more on the flat rate pension

Speaking about the education funding formula Mr Osborne calls it "perverse". He adds that "it cannot be right" if a child receives £3,000 less than another child even though they are in the same circumstances.

"The fact is, it's difficult to save money," Rupert Harrison, George Osborne's former chief of staff, tells Andrew Neil who has asked him about the tax credits U-turn.

"Inevitably, when you're making £100bn plus savings, you're not going to get everything right."

Here's an interesting chart from the OBR. The fiscal watchdog says that taking account of expected underspending against the government’s plans, it expects current spending (RDEL) to be cut by £10.4bn in real terms by 2019-20. That is around 40% less than the £17.9bn cut by that year pencilled in by the government in July and only around a quarter of the £41.9bn peak cut pencilled in by the coalition in March (which was to be delivered a year earlier in 2018-19).

George Osborne attacks the SNP Scottish government's spending choices. "They have used the money they have taken from the university sector to fund free prescriptions for millionaires."

The National Landlords Association responds to the chancellor's announcement that stamp duty land tax on buy-to-let property purchases is to be increased.

Chief executive Richard Lambert said that if George Osborne wants to "wipe out" buy-to-let, he should just say so.

SNP MP Stewart Hosie says the government aims for public spending at "36% to 37% of GDP" which, he claims has not been seen "since the 1930s and 1940s". The chancellor will have to "cut £40bn a year more than he needs to" to ensure a budget surplus, Mr Hosie says, adding: "The people of Scotland did not vote for a decade of austerity."

Public sector net debt should fall as a share of GDP every year of its forecast, and there should be a surplus of £10.1bn in 2019-20, the OBR says, external. But the government is set to breach its self-imposed welfare spending cap after a reversal of the July tax credits cuts and "slow progress with disability benefit reform".

SNP Treasury spokesman Stewart Hosie notes that Conservative MPs cheered the announcement that tax credits cuts would be scrapped, yet says they were "cheering for the implementation" of the cuts not so long ago.
