Costa Coffee is launching limited-edition rainbow cups across the UK to celebrate Pride month.

The high street coffee chain has shown its support of Pride in previous years with everything from rainbow lattes to kaleidoscopic store signs at key locations.

And this year, their allegiance to the LGBT community shows no signs of abating.

The new, "fully recyclable" rainbow cups are being replaced in support of GLOW (Gay Lesbian Out at Whitbread), a group at Costa’s parent group Whitbread which champions equality and inclusion in the workplace.

“Our all-new rainbow cups are a fun way to celebrate Pride and reflect Costa Coffee’s values of equality, and diversity,” Jason Cotta, Costa Coffee’s managing director UK and Ireland, said in a statement.

“We are passionate about championing team members' rights to work in an inclusive, supportive environment.

“We’re so proud of the achievements of the GLOW team and look forward to seeing them marching at the many of the Pride Parades across the UK.”

Since unveiling the cups on Twitter, Costa Coffee has been inundated with praise by supporters of the LGBT+ community for the launch.

“This is so cool! Great move guys!,” one person wrote.

Another added: “I love this cup”, while someone else commented, “This is amazing.”

However, some fans were disheartened to hear that the roll out of rainbow cups won’t reach all of Costa’s UK stores.

The cups are currently available in selected Edinburgh and Chelmsford stores with plans to launch in London from 2 July, Glasgow from 9 July, Brighton and Leeds from 30 July, and Manchester and Cardiff from 20 August.
