Those dark horses at EastEnders are pretty good at keeping secrets hidden from both viewers and the press right up until the last minute, often surprising us all.

For the past 24 hours however, the soap's Twitter account has been having great fun teasing viewers about something big that is going to be announced today.

It started with this tweet last night...

Then today, they put up this clip featuring the sound of high heels clopping slowly over the pavement.

It's starting to become clear that either a major character is leaving or a former one is returning - we are leaning towards the latter.

Who could it be? We'll have to wait until 8pm tonight (October 24th) after EastEnders when all will be revealed.

*Update: So this is what EastEnders' big announcement was
