Filming on EastEnders at Elstree in Hertfordshire will be postponed "until further notice", the BBC has said.
Other BBC productions including Casualty, Doctors, Holby City, Pobol y Cwm and River City will also be postponed.
In a statement about EastEnders, the BBC said:
In light of the spread of Covid-19, after much consideration, it has been decided that filming on EastEnders will be postponed until further notice. The decision was made after the latest Government update. We will continue to follow the latest news and advice from the World Health Organisation and Public Health England. We have also taken the decision to reduce the amount of episodes we broadcast each week to two, so that we can ensure the audience can continue to enjoy EastEnders in their homes for as long as possible.
