30th Anniversary - 16 to 20 of February 2015
EastEnders bosses have confirmed that the soap will be going live for its 30th anniversary next year.
The BBC show will broadcast a 30-minute live episode as part of its big birthday week in February 2015. In a further twist, all of the other episodes airing that week will also include live elements.
Little more is known about the storylines that will feature in EastEnders' milestone week, but it has been confirmed that the identity of Lucy Beale's killer will finally be revealed.
EastEnders' executive producer Dominic Treadwell-Collins commented: "This is a fantastic opportunity for EastEnders to create a massive national event and one that will enable us celebrate 30 years of EastEnders in spectacular style.
"With live elements to each episode as well as a half hour live episode, it allows us to have a huge amount of surprises for the audience. It is ambitious and exciting and something I know everyone at EastEnders will excel at, as they always do."
BBC One's controller Charlotte Moore said: "BBC One will bring the nation together to celebrate 30 years of EastEnders by going live across the anniversary week. Next February will mark a massive event on the channel by creating the ultimate 'doof doof' and finally reveal who killed Lucy Beale."
Ben Stephenson, controller of drama commissioning at the BBC, added: "After a captivating year of drama in 2014, EastEnders will top this in February 2015 with the most ambitious anniversary any soap has attempted. 'Live week' allows us to keep loads of secrets from the cast, crew and the audience until the very last minute. With shocking reveals and unguessable twists, it's going to be a week that will change Albert Square forever."
EastEnders previously aired a live episode to mark its 25th anniversary in February 2010. The special edition included the death of Bradley Branning and the shock reveal that his wife Stacey was Archie Mitchell's killer.
The programme also had an eight-minute live sequence in July 2012 as part of a special episode which saw Billy Mitchell carry the Olympic Torch through Walford and Lola Pearce give birth to her daughter Lexi.
EastEnders will launch its 'live week' on Monday, February 16 2015.
A show statement teased: "This special week will give a nod to the past and welcome the future. With storylines culminating and big momentous events happening, the EastEnders 30th anniversary will take its place in television history."
