EastEnders is gearing up to celebrate its 30th anniversary in February 2015, and to bring the show's big birthday in with a bang, it will broadcast live from Albert Square.

As well as a 30-minute live episode there will be a series of live elements featured in all the episodes that week.

The special week is set to give a nod to the past with old characters returning and also celebrate the future with explosive storylines culminating.

Viewers should expect big surprises throughout the week and the ultimate 'doof doof' when Lucy Beale's killer is finally revealed.

Executive producer of the soap, Dominic Treadwell-Collins, said:

"This is a fantastic opportunity for EastEnders to create a massive national event and one that will enable us to 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."
