Ms Hartley-Brewer mocked the decision of German Chancellor Angela Merkel, which in 2015 declared all Syrian asylum seekers ready to reside in Germany, regardless of which EU country they joined first.
The radio host beat Ms. Merkel's decision and said, "Nobody bothered to ask people" in Germany.
A party leader said on Monday, Mrs. Merkel will replace the country in 2021 after a catastrophic state election in Hesse.
The party of Angela Merkel, the Christian Democratic Union, which had slumped by 10 percent in the polls this week, won in the Central German state elections only 28 percent of the vote.
Referring to the rise of the right-wing extremist population in Europe, Ms Hartley-Brewer said: "I would argue that Angela Merkel, whom you have just given them by the catastrophic mistake of opening the borders, as in the mass immigration country from Eastern Europe under the Government of Tony Blair. "
She added, "And, funnily enough, people like to have a say in how their country is run and who lives in it.
"And they will punish the politicians who do not let them have their say. We'll just see that.
"Actually, whether you like the people you vote for or not, we should not criticize democratic decisions. The political elite do that's awful lots all the time.
"If you believe that every man and woman should have a voice, let them have their voice and trust them to make the right decisions."
MP Tracy Brabin replied and said, "But it is deeply troubling, these sinister forces are rising."
But Mrs. Hartley-Brewer fired back and said, "No, I think it is extremely disturbing if you just invite a million people into the country without asking for permission.
"I think that is deeply disturbing."
Former Ukip leader Nigel Farage also warned that populism "has not even started" and insisted that the Brexit vote will act as a catalyst for a major anti-establishment movement that will flood the globe.
The populist movement has conquered Europe within the last year. Italy's anti-establishment parties Lega and Five Star Movement formed a coalition in June.
Jair Bolsonaro, also known as the "tropical trump," also won the Brazilian presidential election in October, marking a dramatic step to the right for one of the world's largest economies.
Brazil was the youngest country to turn right after voters elected Mr. Bolsonaro, a passionate populist and former congressman, as their new leader.
Mr Bolsonaro, who outraged many with his frankly homophobic, misogynistic and racist rhetoric, won 55 per cent of the votes in Sunday's runoff – more than 10 points ahead of his left opponent Fernando Haddad.
He won the deeply polarizing elections because of a promise of radical change, and his presidency will probably mean a fundamental change of direction for the Latin American country.
