Other ideas, however, such as the decision to kill off long-standing soap veteran Pat Butcher (Pam St Clement) and Heather Trott (Cheryl Fergison), were not as well-received and prompted heavy criticism.
[10] Of his departure, Kirkwood said "Being the executive producer of EastEnders is one of the most exciting jobs in TV, but it's also the most exhausting - so after two years, I've decided it's time to leave Walford.
