Image source, PAWe're expecting our big Remain campaign event of today - a speech from Gordon Brown - at around 15:00 BST. The hope, from Remain at least, is that it will be a significant intervention, but Vote Leave's Boris Johnson isn't impressed.
"I think it's not a brilliant relaunch when you're relying on Gordon Brown," he said during a campaign visit to Henley.
"I am afraid the former Labour leader, former prime minister, is not in much of a position to comment on this because they, after all, took the decision, he and Tony Blair, in 2004, to relax controls very substantially, and what's happened since then is we have seen considerable rises in our net immigration."
The Welsh economy is "stronger, safer and better off" in the European Union, says a group of top business figures.

This was how it looked, warning that "an Orlando-style atrocity" was more likely if the UK failed to vote to leave the EU.

Leave backers also condemned the tweet, among them Iain Duncan Smith, who told Radio 4's The World at One a short time ago: "A tragedy in America has nothing to do with [the EU debate]... I abhor anybody that tries to make capital out of that."
Mr Duncan Smith did say, though, that Europol has warned that "unless we control migration" there will be "threats to security".

A caller to the World at One tells Iain Duncan Smith that Vote Leave's claim that £350 million a week goes to Brussels from the UK is misleading.
"I don't think it is," he replies, arguing that proportion of that money which is returned to the UK "comes back as directed by the EU Commission".
He says staff at the Department for Work and Pensions, under his leadership, had to "twist ourselves in knots" to be able to spend it as they wanted, not as the EU Commission saw fit.

Why not stay and make the EU better from within, Iain Duncan Smith is asked on the World at One.
"I would love to have stayed and made it better. In fact, I didn't want to leave until fairly recently," he replies.
He says he believed that perhaps reform was possible, especially when the EU was presented with the potential for a UK exit, but none was forthcoming.
"They still don't want to engage or offer up any serious reform," he claims.

The third caller says peace in Europe is taken for granted, but she feels a Brexit would put it on the line.
Iain Duncan Smith says he believes that Nato is "the critical cornerstone" of European peace, not the EU.
In fact, he says Brussels is "causing the tensions now" because of its lack of democracy - rather than being a stabilising influence.
He's then asked about that Leave.EU tweet linking the Orlando attack to the referendum campaign.
"I've no idea about that. You know that we're nothing to do with that organisation," Mr Duncan Smith replies, although he notes that Europol has warned that "unless we control migration" there will be "threats to security".
But he adds:
Quote MessageI think it is completely pointless to try to make something out of a tragedy in America."

Do you believe leaving the EU is going to reduce net migration, the second caller asks.
"Absolutely I do," Iain Duncan Smith replies, but that is met with scepticism from the caller, who discusses the influx of foreign workers to his own industry, transport.
Mr Duncan Smith says its "absurd" to look abroad for HGV drivers. He says he disagrees with Sir Michael Rake, chairman of the BT group, that the UK needs migrant labour. He says he knows there are companies who don't even advertise in the UK before bringing in workers from abroad.
Quote MessageThe reason was, I believe, that they thought they could charge less in wages."

Leave campaigner and former cabinet minister Iain Duncan Smith is answering questions on The World at One.
The first caller asks him whether there's any downside to Brexit, because he feels the Leave campaign are painting a Panglossian picture.
"There are always risks whatever you do," replies Mr Duncan Smith.
He says that, "of course there are risks", but being in EU means making "compromises that do not suit you", whereas outside the EU, the UK could make the choices it wants.
And he adds:
Quote MessageThe idea that there is a benign world in the EU and a risky one outside is the problem."
Scotland could be given greater control over immigration if the UK exits the European Union, a leading figure from the Leave campaign claims.

Image source, AFPLabour may be taking centre stage today, but Chancellor George Osborne has still been on the campaign trail in Liverpool. He was asked by the BBC whether a degree of panic within the Remain campaign had prompted the "Labour fightback".
"We want to make sure as we approach this vital vote... that all the voices are heard, not just the Conservative government voices - important as they are - but also the voices of the Labour Party, the voices of the union movement," he said.
"So you will hear lots of these voices now in the final run in to this referendum because people need to know that all sorts of different political parties, all sorts of different political opinions, all the unions, businesses, the works, we all agree on this."
Image source, EPAIf Britons vote to leave the European Union it could mark the beginning of the end for the 28-nation bloc and for western political civilisation more generally, European Council President Donald Tusk said.
In an interview with German newspaper Bild, Mr Tusk said radical anti-European forces would be "drinking champagne" if the UK opted for Brexit
He said:
Quote MessageWhy is it so dangerous? Because no one can foresee what the long-term consequences would be. As a historian I fear that Brexit could be the beginning of the destruction of not only the EU but also of Western political civilisation in its entirety."
Education Secretary and Remain supporter Nicky Morgan has reacted angrily to a tweet from Leave.EU - the unofficial Leave campaign - linking the referendum campaign to the gun attack at Pulse nightclub in Orlando.
The tweet suggest voters should opt for Leave to reduce the likelihood of a similar attack in the UK.
