Organised by UK vegan charity Viva!, the day of action will see activists assemble outside Costa Coffee stores to encourage people to opt for plant-based alternatives such as oat, soya or almond milk.
Protests will take place in 40 towns and cities nationwide on Saturday, with activists protesting outside Birmingham Snow Hill Station’s Costa Coffee on Colmore Row between 11am and 1pm.
Campaigners will be handing out leaflets, holding placards and having conversations with customers about why and how to choose plant-based milks.
They claim the action follows an alleged recent undercover investigation into a farm which reportedly supplies milk to Costa Coffee.
Costa Coffee has been contacted for comment.
