"Holby was a stalwart with viewers, delighting millions of viewers per week and winning countless awards with a persuasive mixture of cutting edge medical stories and volatile private stories.
"We anticipate working with the staff within the coming months to make sure that if it finishes, Holby goes out on a top."

"These programs will get us nearer to viewers, create investment and jobs, and create and cultivate new talent"
