Multiple outlets report that 78 Labour MPs do not publicly back Andy Burnham as the next UK Prime Minister. The coverage lists the MPs who did not make public endorsements, including several Welsh MPs highlighted by WalesOnline. Manchester Evening News similarly states that the total number of Labour MPs not backing Burnham is 78 and references the party MPs without publicly supporting his bid.
The reports frame the information as a snapshot of public backing rather than a full tally of private views or formal votes. They indicate that the relevant data concerns which MPs have not publicly endorsed Burnham, and they provide a list of those MPs. However, the summaries provided do not include specific names beyond noting the inclusion of Welsh MPs in the wider figure.
Overall, both sources agree on the central figure—78 Labour MPs not publicly backing Burnham—and the nature of the measure—public endorsements (or lack of them).
