The policy, introduced in 2017, was widely criticised by campaigners and charities.
Chancellor Rachel Reeves said: “Every child deserves an equal chance to fulfil their potential and for every child that grows up in poverty, we all pay the price.
“When children go hungry and cold, talent goes to waste and we all lose out.
“That is why I’m proud that we will lift more children out of poverty in a single Parliament than any other since records began.”
The Government estimates that ending the cap will lift 450,000 children out of poverty, rising to more than 500,000 when combined with other support.
In Barnet, 10,220 children are expected to benefit from the change.
The two-child limit has been described by the Prime Minister as a “failed social experiment” and around 300,000 children are in poverty directly because of this policy.
The Chancellor also confirmed plans to remove the so-called “rape clause,” so women no longer need to prove non-consensual conception to access support.
Bridget Phillipson, education secretary and co-chair of the ministerial taskforce on child poverty, said: “The evidence is clear – for too long, poverty has been an immovable barrier to opportunity for far too many children across this country.
“Now, we’re breaking it down.
“We’re removing the two-child limit and the cruel ‘rape clause’ policy to restore dignity to the lives of families across our country, which also means more teachers focused on teaching and more children focused on lessons.
“We choose to show children that no matter your background, whether you’re the third child born into your family or not – this government sees you, we value you, we back you to go on to do all you can achieve in life.”
The policy change is part of the Government’s broader child poverty strategy, which will be published in the coming weeks and will set out action to boost family incomes, cut the cost of essentials, and strengthen local support services.
