Katie McGlynn has left the soap – just one day after co-star Faye Brookes announced her departure.
Katie, 25, who has played Sinead Tinker on the cobbles since 2013, “will need replacing urgently” after being central to a number of key storylines this year.
The actress has become the sixth cast member to leave this year as the show’s crisis deepens.
A source told The Sun: “Katie has just been nominated for a British Soap Award so it’s a big loss and not what bosses would have wanted to hear.
“She’s been central to a number of key storylines this last year or so and will need replacing urgently.”
Faye, who plays Kate Connor, said she was "off to pastures new" after four years on the soap.
She tweeted: "Thanks to everyone for your amazing support, but after four fabulous years in Weatherfield it's time for me to explore new opportunities.
"I've loved playing Kate Connor but she needs a break for a little while and so with a song in my heart I'm off to pastures new."
Katie and Faye aren't the only Corrie stars to part ways with the programme after boss Kate Oates left.
Tristan Gemmill, Connie Hyde, Kym Marsh and Bhavna Limbachia have all publicly announced they were leaving Corrie since the start of 2019.
