A power struggle between the House of Commons and the House of Lords is underway after a motion to delay £4.4 billion of tax credit cuts while an impact assessment is carried out was voted in on Monday.
Following the vote Downing Street has confirmed a rapid review of the House of Lords will take place and Chancellor George Osborne has insisted he will press ahead with changes to reduce the welfare bill despite opposition.
They are not there to interfere with the settled will of the House of Commons, warned Boris Johnson.
A working mum who would be hit by Tax Credit cuts spoke to ITV News ahead of the House of Lords vote on the changes.
Peers will have to decide whether to delay changes to the tax credits bill, review them or scrap it altogether.
