Anti-discrimination group Kick It Out will mark its 20th anniversary with a season-long campaign of events and have made it non-compulsory for players to wear their T-shirts. Previously the campaign group has held a two-week period of action in October.

"Kick It Out is above and beyond simply wearing a T-shirt," a spokesman said.

Instead of using the T-shirts, Kick It Out wants clubs to consider how they can promote the campaign, although some clubs have suggested they will still wear the tops.
