characters include Holby NHS trust chairman Terence Cunningham (Roger Barclay), staff nurse Mary-Claire Carter (Niamh McGrady), consultant plastic surgeon Sunil Bhatti (Silas Carson), psychiatric registrar Sarita Dubashi (Rakhee Thakrar), agency nurse Kieran Callaghan (Barry Sloane), who served as a love interest for Donna, and Foundation House Officer 1 (F1) Lulu Hutchison (Fiona Hampton). Several cast members departed during the course of the series. Kensit resigned from the show during its twelfth series and departed at the end of 2010, having filmed her final scenes on 8 October 2010. She stated that she had had a "fantastic time playing Faye but [...] felt it was the right time to move on." Mealing resigned during 2010 after six years in the role of Connie. Campbell deemed Mealing "an invaluable asset" to the series, commenting: "She created an iconic character and Connie will not be forgotten. Connie will have a dramatic but heart-warming departure which will tie into the dramatic entrance of an exciting new regular character." Roberts also announced his resignation in 2010, after being cast in Pirates of the Caribbean: On Stranger Tides. He filmed his final scenes for Holby City in September 2010. Quarshie took a break from the series when Ric was written out to recuperate from his cancer treatment. Powell also departed from the series to return to working in theatre, explaining: "I've been there for six years, and that was five years longer than I ever anticipated staying, and it just struck me that it was probably time to move on and go back to [my] roots." Jacobs left the show in March 2011, after seven years playing Donna. As the series had seen the departure of so many cast members, and the introduction of many new ones, Jacobs deemed it "a new era with a new cast", one which she was not part of, and stated that the time felt right to leave. Catherwood departed the following month, when her character Penny was killed off.
