1400, UPDATE: The technical problems should have been resolved now. The complete live blog is now showing below.
1346, PH: Cameron sits down, and we'll sign off. Apologies, again, for the technical problems - I filled in some of the gaps below. More from Coffee House soon.
1335, PH: Technical problems still very much getting in the way, but it's worth noting that Cameron has started his response. His key message, so far, is the right one: that lower borrowing forecasts aren't much to shout about when borrowing and debt is so high. He also highlights how some of the goverment proposals were made by the Tories first.
1325, PH: Apologies, a few technical problems are slowing things down and have deleted entries between 1302 and 1315 [UPDATE: they've been added below now]. Should hopefully be up and running again shortly. What did you miss? New measures for small business including a new a further £94bn worth of loans from RBS and Lloyds next year; a new credit adjucation service which threatens to become a legal minefield; and a new business investment fund. Also, there's more money for roads, railways, green energies and universities. Oh, and higher duty on alcohol.
1315, PH: There the business tax cut I was hald-expected yesterday: business rates will be cut by 1 percent, for one year, from October.
1314, PH: More than a hint of central planning to Darling's growth plan. The government will ensure that 15% of government contracts go to small businesses
1307, PH: Will we get the spending cuts we need? Well, let's just say that Darling is using the words "efficiency" and "savings" a lot. One of his measures to to relocate civil servants outside of London. He says that civil servants in the capital will be cut by a third - which sounds like a diluted version of the Tories' plan to cut Whitehall bureuacracy by a third.
1303, PH: Claims that government tax measures will raise £19bn for "cutting borrowing".
1302, PH: No changes on VAT, national insurance etc. But higher duties on alcohol.
1301, PH: Darling's rattling through tax measures for higher earners - he adds that these measures aren't implemented out of "dogma or ideology". Laughter from the Tory benches.
1300, FN: Listen to him milking the sole piece of good news - a revision of PSNB from £178bn to.... to.... oh let him talk for a bit more about tax revenues being higher than expected ... £167 billion. Shows what a poor condition our economy is in that an overspend of £160bn - 12% of GDP, unprecedented in our peacetime history - is regarded as some kind of triumph.
1258, PH: Darling says that the deficit-reduction plan is now the fastest of any G7 country. Brown claimed this a few weeks ago, and it was untrue, so this figure should be claim with extreme caution.
1256, PH: Darling says that higher-than expected tax receipts mean that borrowing this year is £167bn (it was £178 in the PBR). It will be £163bn next year. And the upshot is it will be £8bn lower than the PBR forecasts in 2014-15. Darling adds that this means overall debt will be £100 billion lower in 2014-15 . This is what Labour will try to push: but remember debt will still be pushing 1.7 trillion. That's hardly worth cheering about.
1245, FN: Trying to make light of the appalling spike in UK inflation (note how he doesn't list European comparisons here - I wonder why not!). Why does he think it's so high? Might QE have anything to do with it?
1244, FN: Listen to Labour roar in approval with stamp duty of 5% on properties costing £1m and more. Good bit of class war.
1253, PH. Now there's a surpise: Darling downgrades his wildly optimistic growth forecasts for next year. Not by much though: from 3.5 percent to 3-3.5 percent. Still looks a bit fanciful to me.
Brown's tie matches Harman's jacket, a rare example of joined up government from this administration
1250, PH: A double-whammy of copied Tory ideas. Darling says that the government will start reconsidering retirement ages. And Darling says that he will double the stamp duty holiday to £250,000.
1249, PH: Now Darling's setting out some of Labour's "guarantees": training or work for 24 year-olds, that kind of thing. Worth looking for how much these guarantees will cost.
1246, PH: Darling says that a "decade of welfare reform" has limited unemployment during the recession. I wonder what Frank Field would say about that. And, indeed, the 5.4 million people on out-of-work benefits - a figure which has remained constant since 1997. Around a million of those have been on benefits for 12 years.
Tax has raised twice as much as forecast because it failed in its stated aim, to change behaviour
1242, PH: This sounds more bluntly political than Darling's other Budget speeches - there are plenty of nods towards "do nothing Tories". In the meantime, there's little meat on the bone.
1242, FN: "We intend to get all taxpayers' money back" - that's not what the FSA has said in its report estimating what the net loss will be due to the Singer and Friedlander interventions - ie, what the taxpayer is formally forecast to lose. I wonder if No10 knows that the FSA has done this? Gives the lie to Darling's line about getting the money back.
"A storm which began in America spread rapidly around the world" - nope, the UK economy was geared up to a dangerous level by a reckless Chancellor.
"Economic disaster was averted" - depends if you consider the trebling of national debt burden as a disaster or not....
1240, PH: He claims that a tax on bankers' bonuses has raised £2bn - "more than expected". Let's see how that gets used.
1237, FN: He's using the changing forecasts and hailing that as a victory. The words "straws" and "clutch" spring to mind.
1236, PH: Now Darling's into the "global problems" bit of his speech. He says that the government's "unprecedented action" has staved off the worst of the recession - and drops in some innuendo about the "do nothing" Tories.
1235, PH: Darling says that a £2.5 billion "growth package" will be at the centre of the Budget.
1234, PH: Darling's intro is straight from the Brownite copybook. He talks about taking the "big choices," and "protecting the recovery". He adds that borrowing forecasts will be lower than they were last year.
1233, PH: Darling steps up to the dispatch box. For what it's worth, he's wearing a dizzying spotty tie.
1230: So that's PMQs done with. Now to the day's main event: the Budget.
