Andy Burnham has faced sustained criticism after suggesting at Prime Minister's Questions that "majority public support" could trigger a second Scottish independence referendum, with critics accusing him of reopening constitutional divisions unnecessarily. Shadow Scottish secretary Harriet Cross has written to the Prime Minister demanding he explicitly rule out another referendum during his time in office, reject calls from First Minister John Swinney for further talks, and confirm his opposition to breaking up the United Kingdom, warning his "reckless and naive" remarks had handed the SNP a fresh opening to press for another vote.

Burnham had compared Scotland's position to Northern Ireland, where a legal threshold exists for a border poll, and said the only barrier to another Scottish referendum was a lack of "clear consensus". Swinney seized on the comments, noting they marked a shift from Labour's previous stance, and called for talks on establishing an agreed legal mechanism similar to Northern Ireland's. Cross countered that the SNP's failure to win an outright majority in May's Holyrood elections showed voters did not want a repeat of 2014, citing falling school standards, high drug deaths and NHS waiting lists as more pressing concerns. Burnham later wrote to Swinney seeking to clarify his remarks, stressing Scotland and Northern Ireland have distinct constitutional arrangements and reaffirming that independence remains "off the table".
