The Conservatives have called for an investigation into Keir Starmer’s beleaguered chief of staff, Morgan McSweeney, after allegations he tried to mislead the elections watchdog over donations to a Labour thinktank he ran while in opposition. The organisation, Labour Together, was fined £14,250 by the Electoral Commission in 2021 over its handling of almost £740,000 of donations. “It shows how authorities may have been misled over hundreds of thousands of pounds of donations used to install Starmer as Labour leader. If you do not have an account, we will create a guest account for you on theguardian.com to send you this newsletter. Since this time, we have taken measures to ensure Labour Together is fully compliant with all Electoral Commission regulations.”An Electoral Commission spokesperson said: “The commission thoroughly investigated the late reporting of donations by Labour Together and published our findings in 2021.
