Sir Keir Starmer was tonight accused of breaking Commons rules over his relationship with controversial chief of staff Morgan McSweeney.
The Conservatives said the Prime Minister may have broken the MPs' code of conduct by failing to declare past support from the Labour Together think-tank, previously run by his chief of staff.
Mr McSweeney is facing questions about why he hid more than £700,000 in donations to the think-tank – which played a key role in Labour's election campaign.
Labour Together has repeatedly boasted about the role it played in helping Sir Keir win the Labour leadership in 2020 after the party's crushing election defeat the previous year.
But official records show Sir Keir did not declare any support from the group in the official Commons register.
