Sir Keir Starmer is set to reveal plans to turn the Union Jack into a "symbol of inclusion" in a major speech on Friday.
The Prime Minister is expected to bid to "reclaim the flag" from the "far-right" in his final address before the Labour Party conference begins.
His speech will come just days after Tommy Robinson's "Unite the Kingdom" rally drew huge crowds to London, and as flags from across the Home Nations continue to fly across Britain.
Sir Keir will be "keen on reclaiming the flag," a No10 source told The Telegraph - echoing his words from St George's Day.
"The flag is for all of us. It should be a symbol of unity rather than a symbol of division. A symbol of pride, a symbol of inclusion."
But then, the PM will attack Nigel Farage as a "toxic" force, whose idea of Britain must be challenged.
He will also extend his hand to left-wing leaders around the world, and urge them to "fight for the values they hold dear: decency, tolerance and respect".
On several occasions, Sir Keir has pointed to football as an example of his apparent pride in the Union Jack and St George's Cross.
And last weekend, he wrote in The Sun that attending Euro '96 "felt like we were part of something larger than ourselves".
Sir Keir continued: "An England that belonged to our grandparents and our history, but also to our children and our future.
"And I felt like I was part of it. That's the power of our flag. To make us all feel like part of Team England."

Highlights from Donald Trump's extraordinary attack at the United Nations
In case you missed it, Donald Trump launched a scathing attack on leaders at the United Nations (UN) and Sir Keir Starmer yesterday.
After the teleprompter failed, the US President started criticising the UN, saying: "I ended seven wars, dealt with the leaders of each and every one of these countries, and I never even received a phone call from the United Nations."
Key moments from Mr Trump's speech:
- Mr Trump pushed back on countries recognising the state of Palestine, saying it would be a "reward" for Hamas
- The US President urged Europe to "step it up" and impose "a strong round of powerful tariffs" on Russia, to help end the war in Ukraine
- Mr Trump told European leaders that their "countries are going to hell" due to "uncontrolled migration"
- Sadiq Khan is a "terrible" mayor, according to the US President, as he claimed "Sharia Law is coming to London"
- Mr Trump described climate change as "the greatest con job that ever perpetrated on the world", as he hit out at UN bodies for wind farms and other renewable energy projects
Shabana Mahmood warns far right rhetoric 'is getting out of control'
Shabana Mahmood warns that the far right rhetoric 'is getting out of control'
| GETTYHome Secretary Shabana Mahmood said the rhetoric of the far right "is getting out of control" as she pledged to improve border security.
Ms Mahmood said she will "do whatever it takes to secure our border" and fight any legal challenges to prevent deportations.
She told ITV: "If we have got control of our borders, I think that creates the space for fundamental, decent, British people to be welcoming of those who come to our country and to contribute.
"I think that having a secure border is necessary for maintaining what is actually very positive race relations in our country.
"I am also worried about the rise of the far right, I'm very worried about some of the rhetoric, I think it is getting out of control and I worry about where that may lead.
"As politicians, we should hold the line on what is patriotism and what is nationalism; there is a line there - I know where it is."
Keir Starmer's chief of staff faces calls for police probe over £700k donations scandal
Sir Keir Starmer's chief of staff, Morgan McSweeney, was told to label hundreds of thousands of pounds of "hidden" donations as an "admin error", according to a newly-leaked email.
Mr McSweeney is facing growing pressure over his substantial donations to his Labour Together campaign group, which helped Sir Keir win the party's leadership election in 2020.
The Electoral Commission (EC) previously slapped the group with a fine in 2021 due to its handling of donations.
Mr McSweeney was instructed by a senior Labour lawyer, Gerald Shamash, to drop a claim that he had been told donations worth some £739,492 did not have to be declared, the Daily Mail revealed.
On Labour's agenda: Thousands to receive 'life-changing' support through new £25million 'youth hubs' drive
Thousands of young people could receive "life-changing" support into work or training through a new rollout of youth hubs across the country.
Britain's top football clubs have signed up to help ensure every 18-to-21-year-old has the chance to "earn or learn" - with England's Premier League now backing the drive.
The hubs, hosted by sports clubs and community venues in England, Scotland and Wales, are now set to almost double in number thanks to a £25million investment announced today.
The EFL in the Community and Rugby Football League have also been confirmed as new partners, supporting the same aim.
Work & Pensions Secretary Pat McFadden will be speaking to GB News from 9am to discuss the hubs - and more - and you can follow his appearance on this live blog or on our live stream HERE.
Liz Truss backs Donald Trump's dire migration warning to Britain and warns: 'We NEED to wake up!'
Liz Truss has come out to back Donald Trump after he warned that Britain and Europe were "going to hell" over migration.
The President had told the UN that "it's time to end the failed experiment of open borders" - and attacked Europe's net zero policies to boot.
Now, the ex-Prime Minister has said: "Trump is right to take on the failed globalist order.
"Net zero, mass migration and curbs on free speech are killing Britain. We need to wake up before it's too late."
