To ask His Majesty's Government what policies and guidance are in place for Network Rail concerning whether political statements are permitted in advertising or otherwise displayed in their stations.

All advertisements and any displays in Network Rail’s stations must comply with Network Rail's code of acceptance for commercial advertising. The code states that any displays ‘will not be approved for or permitted to remain on display if they are of a political nature calling for the support of a particular viewpoint, policy or action or attacking a member or policies of any legislative, central or local government authority’. Advertisements must also comply with the ASA’s British Code of Advertising Practice.
