David Cameron, still full of beans as he bounds on to the stage in Enfield, begins by saying he’s “very excited” by the “men in blue coats” - better than white ones, we guess. Here we go again.

Here’s the background to today’s Court of Appeal defeat for the Independent Parliamentary Standards Authority, to give Ipsa its full title. It stems from a Telegraph journalist’s 2010 complaint that Ipsa would only provide a summary of the information contained in MPs’ expenses receipts, rather than copies of the actual receipts themselves. The information commissioner ruled in the journalist’s favour in 2012, after which Ipsa lost two tribunal decisions before today. The ruling is a significant one, Ipsa’s lawyers have argued, because it will have an impact on all public authorities.

Chief Secretary to the Treasury Danny Alexander has been repeatedly pushed by Victoria Derbyshire on what impact the Lib Dem's £12bn of cuts would have on public services.

"As you make government more efficient... if you're using more technology then you need fewer people," he said - but declined to put a figure on the number of potential job losses.

The Daily Telegraph's Matthew Holehouse helpfully summarises some top lines from the Institute for Fiscal Studies briefing going on right now. We'll bring you more when we can.

Expenses regulator Ipsa has lost a Court of Appeal challenge against an order that it must release copies of receipts submitted by politicians.

Rumours flitting around about Russell Brand possibly backing Labour - rumours which, we should underline, are completely unsubstantiated thus far - are prompting all sorts of speculation about other big-name endorsements. The Mirror’s Heckler column points out that the Conservatives have printed a picture of none other than Mick Jagger alongside David Cameron in Jagger’s home town of Dartford in Kent. Perhaps the Rolling Stones frontman is about to make a late career change? “Mick’s position has not changed,” a spokesman is quoted as saying. “He remains affiliated to no party.” Wishful thinking on the part of local Tories, perhaps.

UKIP’s Suzanne Evans has hit out at Labour as Ed Miliband pushes his party’s 10-point plan to tackle immigration today. Ms Evans, appearing at a press briefing this morning, said Labour had "deliberately tried to change the demographics of British society" when it was in power and "used race and religion" to get people to vote for the party. “I simply don't believe that they want to control immigration,” she said. "The fact we've had Labour MPs and candidates running around, refusing to hold that Labour mug saying 'we will control immigration' despite the fact it's apparently been a major plank in their manifesto - I simply don't believe them.”

Chief Secretary to the Treasury Danny Alexander offers a Lib Dem perspective on this morning's GDP figures:

28 April 2010 was not a good day for the Labour. Some believe it might even have cost the party its grip on government. For this was the day that defined the 2010 campaign - the day on which Gordon Brown made his agonisingly bad gaffe of being caught on a microphone saying the pensioner he’d just spoken to about immigration - Gillian Duffy - was a “bigoted woman”. He was pictured with his hand on his forehead while the tape was played back to him, before dashing round to her house in Rochdale to apologise.

There’s been nothing like ‘bigotgate’, as it came to be known, in the 2015 campaign yet - in part because the party leaders are being held back from encounters with the general public in the way they were in 2010.

Here’s a bit more detail on the GDP figures from the Office for National Statistics, external. The decrease in the rate of growth from 0.6% to 0.3% is mostly down to a 1.6% slip in construction, although output in the services sector was up by 0.5%. Production slipped by 0.1% and agriculture was down to 0.2%. Looking at the big picture, the economy is now 4% larger than its pre-downturn peak.
