ITV has confirmed it will not return to its traditional South Bank location following the site's redevelopment.
The broadcaster moved out of the site earlier this year, and was expected to return following the planned five-year redevelopment.
Instead, ITV chief executive Carolyn McCall has decided to sell the site. ITV bought the freehold of the complex in 2013 for £56 million.
"Since the original decision to redevelop the South Bank site ITV has launched its new strategy and has successfully moved to new office space in Holborn and studios in W12," a spokesperson explained. "These provide excellent modern, functional and flexible working environments.
"TV needs to ensure that its property portfolio in London supports the new strategy by giving flexibility to continue to grow, while supporting our ambition to be an agile and increasingly digital organisation.
"By remaining in our current London office and studio spaces we can focus more time and resource on the areas of the business which will deliver greatest value."
ITV moved its live programming, including Good Morning Britain and This Morning, to Studioworks at Television Centre. It's thought this arrangement will continue.
