Former Labour leader and Remain support Gordon Brown says the Brexit campaign's slogan is "leave Europe, join the world".

However, he adds, the leaders of other nations outside the EU are calling on the UK to "stay in Europe".

Mr Brown says Leave campaigner Michael Gove claimed Albania wanted to leave the EU, "then the Albanian prime minister said he wants us to stay in Europe".

"Who's left? Donald Trump?" he adds.

Mr Brown says his vision of the UK is "not isolationist and insular but internationally-minded".

Gordon Brown says the UK cannot combat terrorism and improve security "unless you're prepared to work with your neighbours". He claims that "even the Eurosceptics" accept the need to work across Europe on security.

The former PM says there is a problem with illegal immigration into the UK, due to traffickers and gangmasters:

Home Secretary Theresa May describes the assault on an Orlando gay nightclub as "utterly evil".

She is responding to an urgent question from Labour's Stephen Doughty on the UK's security in light of the shootings in which 50 people were killed, the deadliest mass shooting in US history.  

Gordon Brown says the EU sets "social standards" that the US and others do not.

"If you're going to avoid the employee being undercut or exploited, you don't want the good employer in the UK being undercut by the bad employer somewhere else," he says.

He suggests that "bad employers" stand to gain from a UK exit from the EU.

He also says membership of the EU will help the UK to deal with "the scandal of tax havens across the world".

Referring to Labour's time in government, he says: "I wish we'd known about the scale of abuse" revealed in the Panama Papers.

Home Secretary Theresa May condemns violence surrounding England's game against Russia as "deeply disturbing". 

She says she has "no doubt coordinated groups of Russian fans bear heavy responsibility" for what happened but some English fans behaved "inexcusably"  and will face heavy penalties. 

Shadow home secretary Andy Burnham joins her in her condemnation and speaks of "severe failings" in security arrangements.

The UK cannot deal with many of the problems in the world "without co-operation with your neighbours", former PM Gordon Brown says.

"The European Union is not the cause of the problem but, if you can get co-operation working, the European Union can be part of the solution to the problem," he insists.

"Yes, we want to trade more with China and India," Mr Brown says, but he argues that the growth of IT and other industries in Europe mean "British jobs will be created".

He predicts the creation of up to 500,000 more "high quality jobs" if the UK stays in the EU.

Former Prime Minister Gordon Brown tells a few jokes about former Labour Foreign Secretary George Brown (no relation) who was known for being, euphemistically, "tired and emotional" at times.

Gordon Brown tells his audience that George was overheard offending the then-President of France, Charles de Gaulle, "because politicians have problems with microphones" - a reference to his own travails in the 2010 election campaign with Gillian Duffy. 

He adds:

"The EU has promoted the undercutting of wages and the social dumping of cheap labour, leading to the decimation of UK sea-faring jobs" says Mick Cash, of the RMT union.

In the run-up to the EU referendum, the Daily Politics has offered a dozen key figures the chance to take to their soapboxes and make short films on the case for either remain or leave.

Gordon Brown begins his speech at Leicester's de Montfort University. He points to developments in the city "supported by European Union funds" and gets a round of applause for praising Leicester City's recent Premier League victory:

European Council President Donald Tusk has warned that Brexit could threaten "Western political civilisation".

Reacting to those remarks, pro-Leave minister Priti Patel said: "This is extraordinary language from the EU president, and serves only to reveal his own desperation."

The condemnation of that Leave.EU tweet keeps coming, despite it having been deleted. The chair of the Vote Leave campaign - a separate organisation altogether - Labour's Gisela Stuart said:

The Conservative former cabinet minister, Norman Fowler, has been elected as the next Lord Speaker.

He will take his place on the woolsack on 1 September, replacing Baroness D'Souza.

The shadow leader of the House of Commons, Chris Bryant, says Labour leader Jeremy Corbyn will be among the MPs attending tonight's vigil in London for the victims of the Orlando shootings.

London Mayor Sadiq Khan is also reported to be attending the vigil in Soho.

Treasury Committee chairman Andrew Tyrie announces he will back the Remain campaign in the EU referendum, saying Brexit will be likely to lead to a "short-term economic shock".

The main stories today so far:

- Gordon Brown is set to make a "positive case" for EU membership, arguing that Labour voters have most to gain from staying in, if the EU is able to be a vehicle for tackling corporate tax avoidance, creating jobs, and lowering energy bills

- But Leave campaigners have dismissed Mr Brown's intervention. Iain Duncan Smith said Labour was "lecturing" rather than listening to its own supporters over immigration

- Elsewhere, European Council president Donald Tusk has warned that a vote to leave the EU in the UK referendum could threaten "western political civilisation"

- Unofficial campaign Leave.EU has deleted a tweet which linked the gun attack at an Orlando nightclub with the referendum. It has been called "shameful and "cowardly" by Remain supporters, and also condemned by Leave campaigners, including Mr Duncan Smith

- BT bosses and union leaders are sending a joint letter to staff saying they want the UK to stay in a reformed EU

- Migration Watch, a think tank that wants lower immigration, has published a study forecasting net migration to the UK would run at more than 250,000 a year for at least 20 years if the UK stayed in EU

- Treasury Committee chairman Conservative MP Andrew Tyrie has announced he will back the Remain campaign

- Labour sources say Alan Johnson has written to broadcasters to protest at the lack of coverage for the Labour campaign

BBC News Channel

Labour's Hilary Benn is scathing about Leave.EU's now-deleted tweet linking the Orlando attack with the referendum campaign.

He calls it a “shameful and cowardly” act from "Nigel Farage’s Leave.EU campaign".

"I think it's disgusting and I think Nigel Farage owes all of us an apology," the shadow foreign secretary told the BBC News channel.

Mr Benn continued: "It's a catastrophic mistake... yes they've deleted it, but what possessed them to do it in the first place?"

The UKIP leader is a supporter of Leave.EU, the unofficial Leave campaign.

Speaking of Labour's so-called "relaunch", Stephen Bush, writing for the New Statesman, says criticism of Jeremy Corbyn, external over the EU referendum campaign is unfair.

"The idea that Corbyn’s lack of enthusiasm is Labour’s main problem is superficially attractive for nervous pro-Europeans as it does at least have an easy solution, unlike, say, the thorny question of how you win a referendum on immigration in which the cultural headwind is against you, or on the economy when not enough voters are feeling the benefits of the recovery, such as it is," he writes.

But he says Labour "got a leader who is not het up about the European Union because that’s what they voted for", adding: "All the evidence is that even if they did have a committed pro-European, they would struggle to get the attention they badly need to get their voters to the polls."

The Lords will begin their day at 2.30pm with the result of their election for a new Lord Speaker. 

The election was held on Wednesday 8 June, but - as with the Speakership of the Commons - the result could not be confirmed until the winner had received the Royal Approbation, the approval of the Queen. 

From there on, it's a fairly disjointed day in the House of Lords. Most of the day will be taken up with debate on reports from two select committees: the Digital Skills Committee and the European Union Committee report on EU energy governance.  

Between the two select committee report debates, Lord Ahmad of Wimbledon will repeat the statement on the UK's security in light of the shootings at a gay nightclub in Orlando - followed by 10 minutes of question and answer.

The end of the day will be taken up with short debates on a several Orders and Regulations making amendments not deemed major enough to warrant primary legislation.

First the Statutory Auditors and Third Country Auditors Regulations 2016 (the draft 2016 Regulations), which will implement the Statutory Audit Amending Directive, external and EU Audit Regulation, external in the UK. 

Then peers will debate a series of amendments to Access to Justice Act which would change the path of appeals through the courts in Civil and Family Courts.

House of Commons
Parliament

The Commons opens at 2.30pm with Home Office questions - and after that the government will respond to an urgent question from Labour's Stephen Doughty on the UK's security in light of the shootings at a gay club in Orlando in which 50 people were killed.

MPs then move on to report stage proceedings on the Policing and Crime Bill, external. 

Labour will have amendments down on a series of "victims' rights" issues - some inspired by the findings of the recent inquiry into the Hillsborough disaster. 

Also under the microscope: 

• treatment of mental health in the criminal justice system

• the use of tasers on psychiatric wards
• referrals of children the police or a local authority think have been sexually exploited
• creating the offence of abduction of a vulnerable child aged 16 or 17 
• prevention orders to stop grooming for criminal behaviour. 
• giving the National Assembly for Wales responsibility for policing 
• creating an offence of knowingly taking a prohibited substance as an athlete
• providing a mechanism for compensation for victims of revenge pornography.

The day winds up with Lib Dem Tim Farron's adjournment debate on the closure of a mental health ward at Westmorland General Hospital.
