There is a huge amount of concern, bordering on panic, in the Remain camp, and nowhere more so than in Number 10. It's an irony of this campaign that David Cameron's fate may well rest in the hands of one Jeremy Corbyn and the Labour Party - and Downing Street are worried that Labour hasn't been doing enough to persuade its supporters to go out and vote for Remain.

So over the next 48 hours we'll see senior Conservative figures take a back seat and allow Labour to try and do what they've not managed to do so far - dominate the news agenda and reach out to core voters.

We'll also see something of a rebranding of the Remain campaign, with a conscious move away from Project Fear to Project Hope. That's the sort of things we'll be hearing from Gordon Brown today.

The big difficulty of all this is that it's late, very very late, and in political campaigns you need weeks and months to drive your message home. The idea of trying to thrash it all together in the last 10 days just underlines how nervous Labour folk are.

Coming from the Leave side of the argument this morning, think tank Migration Watch - which campaigns for tighter immigration controls - is forecasting that net migration to the UK will run at more than 250,000 a year for at least 20 years if the country stays in the EU.

The think tank says there's widespread complacency and denial about both the likelihood and the impact of rapid population growth.

It insists numbers won't come down until the economies of Eastern Europe are similar to the UK's. 

But in response, immigration minister and Remain campaigner James Brokenshire said quitting Europe would damage the economy and that was not the answer to the complex issue of immigration.

Also this morning, bosses at telecoms firm BT and the leaders of the CWU and Prospect unions - which have members among BT's 81,400 staff - are sending a joint letter to staff saying they want the UK to stay in a reformed EU.

They say it is up to staff how they vote in the EU referendum on 23 June but urge them to cast their ballot, arguing the vote will have a big impact on the economy and company.

Vote Leave said talk of a "reformed Europe" was "meaningless and hollow".

We've had a series of political big beasts making interventions in the campaign and today is the turn of former prime minister Gordon Brown.

He is to make a speech later telling Labour voters they have the "most to gain" if the UK stays in the European Union, as the party seeks to rally its supporters behind the Remain campaign.  

Calling it the "positive" case for staying in, Mr Brown will say the EU can deliver policies close to their concerns including tackling corporate tax avoidance and creating jobs.

But the Labour MP Gisela Stuart - who chairs the official Leave campaign - said her party's voters "have now seen through government spin and no amount of hastily cobbled together relaunches" would change that.

Conservative MP Mark Field says a select committee inquiry into the BHS collapse could see Sir Philip Green having to pay millions back into its pension fund. The Conservative vice chairman told the Westminster Hour that a worse threat to the tycoon than losing his knighthood could be a "full inquiry in all his business dealings going back a number of years".
