Members of Parliament voted against establishing a parliamentary inquiry into Prime Minister Keir Starmer's role in the vetting process for Peter Mandelson's appointment to a government position.

The vote followed questions raised about the proper procedures and oversight mechanisms used during Mandelson's consideration for the role. Opposition MPs had called for the inquiry to examine whether appropriate protocols were followed.

The debate centered on what some described as the Morgan McSweeney evidence, though specific details of this evidence were not disclosed in the parliamentary proceedings. McSweeney serves as Starmer's chief of staff.

Mandelson, a veteran Labour politician who previously served in senior government roles under Tony Blair and Gordon Brown, has been a controversial figure due to his past business dealings and political activities.

The rejection of the inquiry means the matter will not receive formal parliamentary investigation at this time. Government supporters argued that existing vetting procedures were adequate and properly followed.
