Alan Johnson’s ex-police bodyguard, suspended over an alleged affair with the former shadow chancellor’s wife, will be investigated over claims of a second relationship, sources said.
Close protection officer Pc Paul Rice guarded Mr Johnson when he was home secretary. He is thought to have worked for Theresa May since she took over at the Home Office last May.
An internal police probe will now look into both alleged relationships, it is understood.
The second was reportedly with a 50-year-old woman in the politician’s Hull constituency.
But this relationship, if confirmed, may not constitute misconduct.
Mr Johnson quit Labour’s frontbench on Thursday, forcing leader Ed Miliband to reshuffle his top team less than four months into the job.
In a statement the following day, Scotland Yard said: “A Metropolitan Police Service (MPS) Specialist Operations Police Constable has today, Friday January 21, been suspended from duty pending the outcome of the Directorate of Professional Standards (DPS) investigation into allegations reported in the media regarding an inappropriate relationship.
“The matter was referred by the MPS Specialist Operations Unit to the DPS on January 20. A thorough investigation is now under way. As the allegation is subject to investigation, we are not able to comment further at this stage.”
Mr Johnson has refused to elaborate on the “personal reasons” for his shock resignation, saying only that he was finding it “difficult to cope” with “personal issues in my private life”.
He has been married to Laura, his second wife, for almost 20 years. The couple have a 10-year-old son.
