Sunak refuses to be drawn on French electionpublished at 11:42 British Summer Time 1 July
Sunak is next asked about the recent success of Marine Le Pen's far right National Rally party in France's election and what that means for the UK.
He tells the audience that, without getting into what happens in other countries, he will lay out the Conservative Party's plan to lower immigration.
The prime minister says the levels of migration in the UK are forecast to halve over next 12 months, adding that he will ensure there is a vote in Parliament to set an annual cap on the number of immigrants.
"When to comes to illegal migration I think it's unfair, I say that coming from a family of immigrants," Sunak says.
He adds that people who come here illegally won't get to stay, making the case for the Rwanda policy to fly some migrants there to "remove the incentive" for people to cross the channel on small boats.
