Sunetra, who plays Zoe Hanna in the medical drama is also known for her appearances in shows such as Doctor Who, Brookside and No Angels.
Sunetra said: “I don’t quite know what I’ve let myself in for… I’m in total denial! But the chance to swap my stethoscope for sequins was just too tempting. I am very excited to be part of the Strictly team!”
Sunetra is the seventh contestant to be confirmed for this year’s line-up and will be joining Mark Wright, Simon Webbe, Thom Evans, Alison Hammond, Judy Murray, Frankie Bridge and eight other celebrities as they compete for the coveted glitter ball trophy.
