Gordon Brown says migration to the UK is "not uncontrolled" and many of those coming in are "skilled people that companies are desperate to employ". 

He says he won't make predictions about the numbers coming in the decades to come and dismisses the forecasts being made by Migration Watch UK today.

When presenter John Humphrys brings up Gillian Duffy - the woman Mr Brown described as "bigoted" after she brought up immigration during the 2010 general election campaign - Mr Brown seems irritated and says immigration is "the BBC's agenda".

Boris Johnson has just been speaking to Adrian Goldberg on BBC Radio West Midlands.

He downplayed the benefits of being in the single market, saying it should really be called the "single legislative system".

While UK firms did export to this market, he believed the UK was better off outside what he described as the "toils of the machine".

On immigration, Mr Brown says he acknowledges that more must be done to help communities deal with the pressures of new arrivals.

But he says countries like Norway, outside the EU, have higher levels of net migration than the UK.

"The biggest problem is illegal migration," he continues, and the only way to deal with that is by co-operating with other EU countries.

Gordon Brown says countries like Norway and Switzerland "receive decisions" from the EU, but don't get a say in them - and the UK must not end up like that. 

The Labour voters that I talk to don't like the status quo, the former PM goes on, which is why, he says, he is keen to persuade them that things can get better in the EU if there is more reform.

Gordon Brown is now on the Today programme ahead of his big speech today. He says history shows that Britain "has always led the way when things have been difficult in Europe and it's time we led the way again".

He says making the argument for renewed British leadership in Europe is "a Labour agenda, but one that Conservatives should accept".

A major Conservative donor has reportedly said he is no longer "prepared to support the current regime" because of the way David Cameron has handled the European Union referendum campaign. 

Edi Truell, a Leave supporter, has donated more than £270,000 to the Tories since 2010 but has written to Conservative chairman Lord Feldman to say he will no longer give the party money, the Daily Telegraph is reporting.

But the City financier said he would be pleased to back former London mayor Boris Johnson, Justice Secretary Michael Gove and "the genuine Conservative Party" in future. 

The pensions expert said the prime minister's warning about the damage a Brexit vote could do to retirement savings was the final straw in a pattern of "unfair" and "irresponsible" claims.

BBC Breakfast

Sir Michael Rake, BT group chairman, tells BBC Breakfast why he and fellow senior executives at the firm have written to staff explaining their support for continued EU membership.

He says the letter talks about “the economic aspects” of the argument, but denies it is a warning that jobs could be lost if the UK backs Brexit. 

Sir Michael does, though, say it would be “very damaging” to take a step that would leave the UK "outside the single market" and “without influence”

"I don’t think it’s a question of influencing staff," he goes on, but says BT, "as a responsible employer", has "an obligation and a right" to set out its position.

Labour sources say Alan Johnson - who is leading Labour's campaign to stay in the EU - has written to broadcasters to protest at the lack of coverage for the Labour campaign.

There has been growing nervousness in Labour ranks that their EU campaign has failed to secure much media attetnion and has been overshadowed by Conservative infighting.

They fear this has made it much harder to get their message over to Labour supporters who could determine the outcome of this referendum.

This comes as the Labour Party today "repackages" its referendum campaign with a much greater focus on the positive benefits of EU membership.

Labour sources have pointed to a recent report by Loughbrough University which concluded that Labour was "almost invisible" in the media during this referendum campaign.

Labour, it was claimed, was present in just 4% of TV coverage and 8% of print coverage; and no Labour figure was among the top 10 most frequently reported figures in this campaign.

A "relaunch" ten days before a vote is not a good sign. But by the main Remain campaign's admission, that is what's happening today, as 'Labour In' beefs up its effort to get its voters to choose to stay in the EU referendum.

Leading Leave campaigner Iain Duncan Smith is asked about Migration Watch UK's projections on Sky News. Remember, the think tank says net migration to the UK will continue to run at 250,000 a year for at least 20 years if the country votes to stay in the UK.

The Conservative MP says the figures come from "a respected organisation" and are a credible forecast because they come in the context of the "incredibly persistent high level of net migration" that the UK already has.

He also says such levels of migration are inevitable because GDP levels in much of Eastern Europe are so low that any job in the UK will bring a significant increase in wages and that is "a huge and enormous pull factor".

Mr Duncan Smith says people like Gordon Brown argue that if the UK votes Remain they can get more reform, can secure some curbs on freedom of movement.

"No you won't. This is it. We had our chance at reform and the European Union said get lost."

The Daily Telegraph

Gordon Brown is promising to make the "positive case" for staying in the EU today, something the Remain camp has so far failed to do, according to the Daily Telegraph's editorial on Monday.

"Its entire message centres on the alleged negative impact of leaving," the paper says.

It continues: "The reason... is that the likely developments in the EU over the next few decades will take it even further away from the institution the UK wants it to be. 

"The status quo is not an option."

Scotland's First Minister Nicola Sturgeon says polls showing a lead for Brexit "should act as a wake-up call to anyone who assumed that it would be an easy win for the Remain side".

"But I still believe there is a majority for an 'in' vote across the UK - especially if everyone who believes in our place in Europe turns out to vote. And Scotland's voice could help to make the difference in this contest, especially if the result is as close as some polls suggest."

But Tom Harris, director of Scottish Vote Leave, said: "I think the Scottish political establishment will be in for a shock if they think we will believe David Cameron's scaremongering."

He said leaving the EU would bring more powers for Scotland, adding: "SNP voters will be wondering why they're being asked to vote against more powers for Scotland, and why they're being asked to continue being governed by an unelected, unaccountable political elite in Brussels which threatened Scotland during the independence referendum."

The Daily Mail also notes the decision by David Cameron "to hand over the campaign to keep Britain in the referendum to Gordon Brown and Jeremy Corbyn", but describes it as "project panic". 

It says the move "echoes the final desperate days of the 2014 Scottish independence referendum". 

"The decision to draft in Mr Brown is a high-risk move, and it remains to be seen whether he has as much appeal to English voters worried about immigration as he had to Scottish voters in 2014," the paper adds.

Financial Times

Speaking of Scotland, Monday's Financial Times says that by bringing in Gordon Brown, "Remain campaigners are hoping for a reprise of his barnstorming crusade in the final days of the 2014 referendum campaign".

The day before the Scottish independence vote, the former PM gave an impassioned speech in support of the United Kingdom.

The paper says Mr Brown's speech will be followed in the coming days by major interventions from Jeremy Corbyn, Hilary Benn, Tom Watson and Harriet Harman "in an effort to claw back support from those who have railed behind the anti-establishment message of the Out campaign".

One of the issues with Labour taking charge for Remain is that they don't really want to talk about immigration because it's too late to change opinions. Therefore, by talking about it all you do is make it the issue and play into the hands of Brexit campaigners.

There is also a danger of Scotland Mark 2 in some of Labour's traditional heartlands in the North where voters have become disenchanted with a party they see as too London-centric, as out of touch, with what they are about. 

Immigration has become a lightning rod for that, a key issue that people rally round and say, look, you just don't get where we're coming from.

In that context, simply getting a few headlines, getting Gordon Brown out, probably isn't going to be enough to turn things around.

We'll also hear today that senior Conservative MP Andrew Tyrie, who chairs the Treasury select committee, is backing the Remain campaign.

The former Treasury adviser will say leaving the EU would almost certainly lead to a "short-term economic shock" and while there are reasonable arguments on both sides, Remain has the strongest economic case.

A Vote Leave source said Mr Tyrie's "pro-EU views were well known" adding: "We wish him well."
