Shabana Mahmood told a "white liberal" heckler to "f**k right off" after she was accused of copying Reform UK policy.
The Home Secretary was subjected to heckling from a man who wanted to "personally thank" Ms Mahmood "for out-Reforming Reform" during a podcast recording in London.
The same recording, which took place in the heart of the capital's West End, also hosted two audience members who shouted "refugees welcome" while the first disrupter was escorted off the premises.
Ms Mahmood did not waste any time on hitting back and declared she would not be "put in her box".
She argued Britons' concerns about mass immigration are "perfectly valid" and slammed the protesters for attempting to "delegitimise" such concerns.
During the recording in the Duchess Theatre, she said: "I do think there is that element of it which is: 'How dare you, a brown woman, say a thing that we white liberals think you’re not allowed to say?’
"Well, I’m saying it,” she boldly declared to the audience, speaking with comedian Matt Forde for his Political Party podcast.
Soon after, her words were interrupted by the man who accused her of "out-Reforming Reform".

Ms Mahmood retorted: "I’m not going to let a tin-pot racist or some random heckler or anybody else claw away at the foundations of who I am as a person.
"I’m a proud Englishwoman. I’m a proud Brit, I’m a hugely proud Muslim. That is the absolute core of my life."
She further shrugged off the accusation her clampdown on mass immigration as merely a way of "delegitimising" her views as Home Secretary as well as the "valid, legitimate view of millions in the country, including ethnic minorities".
"And it’s not acceptable, right?" she continued. "And also, you’re trying to put me in a box, which includes a lot of people who think I don’t even belong in my own country.

“That’s why I said this individual can just f**k right off, because I know I belong in my own country. You’re not going to be able to do that to me.”
Earlier this year, Ms Mahmood told Nigel Farage to "sod off" after he accused her of aping his policing on cutting down illegal migration.
Mr Farage, in the process, cheekily offered up a position for the Birmingham Ladywood MP to join his party - on multiple occasions.
"Nigel Farage can sod off. I am not interested in anything he has to say," the Labour minister slammed on Sky News.
During last night's podcast recording Ms Mahmood continued to defend her migration crackdown despite its burning unpopularity amongst rebellious left-leaning Labour MPs.
Earlier in her tenure, the Home Secretary outlined to the Commons her plans to reform indefinite leave to remain, which decides which migrants come to Britain to work, study and reside.
Under such plans, refugees will have to wait 10 years before they acquire permanent settlement in the UK, instead of the current five, with Ms Mahmood saying the ability to live in Britain was "a privilege".
Refugee status will only be handed out temporarily and will be reviewed every 30 months.
Those who do not qualify as refugee status will be asked to leave the UK while Labour continues its crackdown.
The Home Secretary previously declared her tougher stance on Britain's borders were based on "compassion and control" and was a centre ground between the "extremes" of Reform UK and the Greens. .
She warned rebellious MPs that, should they fight her plans, Reform UK would grasp power at the next possible chance.
