Multiple reports in The Daily Mail and The Mail on Sunday describe an alleged heated argument between Labour ministers Rachel Reeves and her younger sister, Ellie Reeves, at Ellie Reeves’ home during her son’s birthday party. According to the accounts, the dispute involves a political disagreement over whether Ellie Reeves would vote in a way that would allow Andy Burnham to return to Westminster. The reports say the confrontation became so tense that Rachel Reeves eventually left the home, with the incident occurring during the child’s birthday gathering. The articles present the exchange as an “almighty row,” but they do not provide additional official detail or corroboration from other sources within the provided text. Overall, the coverage centers on the timing of the alleged argument—during a family event at Ellie Reeves’ residence—and the specific subject said to have sparked the disagreement: a proposed vote affecting Andy Burnham’s ability to return to Parliament.
