Walker was convicted of a string of domestic abuse charges committed against three ex-wives and a teenage stepdaughter. The former SNP MSP and independent served 6 months of a year-long prison term, and was released in March.
A pass to walk through Holyrood is usually given to MSPs who retire or are voted out, and allows access to the building’s two bars and Members’ Restaurant.
Walker’s application for a pass was knocked back by parliament staff, with one anonymous source telling the Sun newspaper: “He can forget it. The only way that guy’s getting back in here is with a coach tour.”
Last month, it emerged that the wife-beating former politician had lost an appeal to overturn one of his convictions.
