The SNP’s amendment to the king’s speech, which calls for the abolition of the two-child benefit cap, has been chosen for a vote by Speaker Sir Lindsay Hoyle. This crucial vote is set to take place in the Commons on Tuesday evening.

The outcome of this vote could signal the first significant rebellion against Prime Minister Keir Starmer from within his own party. A number of Labour MPs have expressed their opposition to the two-child benefit cap, advocating for its removal.

Former Chancellor John McDonnell is among the prominent figures who have announced their intention to support the SNP's amendment. McDonnell’s decision underscores the internal conflict within Labour, as many MPs argue that the benefit cap disproportionately affects low-income families and exacerbates child poverty.

The two-child benefit cap, introduced in 2017, restricts financial support for families to their first two children, a policy that has faced significant criticism for its impact on larger families. Critics argue that the policy unfairly penalizes children based on their birth order and puts additional financial strain on families already struggling to make ends meet.

Prime Minister Starmer faces a challenging situation, balancing the need to maintain party unity while addressing the concerns of those who believe the cap is unjust and harmful. The vote this evening is seen as a litmus test for Starmer’s leadership and his ability to navigate complex and divisive issues within his party.

As MPs prepare for the vote, there is heightened anticipation about the potential outcome and its implications for the future direction of Labour under Starmer’s leadership. The result will not only reflect the party’s stance on social welfare policies but also Starmer’s ability to command support and manage dissent within his ranks.
