More evidence that Ken Livingstone is joined at the hip with the RMT, the tube union whose strikes cause such misery for London commuters.
This afternoon the RMT issued a press release for a photocall with Labour London Assembly Member Val Shawcross, who is standing as Ken Livingstone's running mate and nominee for Deputy Mayor. This picture is of her at earlier RMT demo.
The press officer issuing the RMT was Joe Derrett – who is also the "Head of Mayoral Press" on Livingstone's team.
