Veronica "Ronnie" Branning is a fictional character from the BBC soap opera EastEnders, played by Samantha Womack. She and her younger sister Roxy Mitchell were introduced by executive producer Diederick Santer in July 2007. Ronnie is described as the "ice" to Roxy's "fire". As an extension to the already established Mitchell family, Ronnie quickly became a prominent character, taking over the square’s local nightclub. She later formed an on-off relationship with her business partner, Jack Branning.

"Who Killed Archie?" is a storyline from the BBC soap opera EastEnders. It began on 25 December 2009, Christmas Day, when the character Archie Mitchell, played by Larry Lamb, was murdered by an unseen person. Events leading up to and following the murder put several characters in the frame, in the style of a Whodunit mystery. The culprit was kept a tight secret within the production crew as well, with only seven people knowing the identity of the killer. The murderer was revealed as Stacey Slater during a live episode titled "EastEnders Live", broadcast on 19 February 2010, the show's 25th anniversary. Turner was told thirty minutes before the broadcast that Stacey was the killer, and actors rehearsed several possible endings. Finally, a two-hander episode between Stacey and her ex-lover Max Branning on 26 March 2010 explained how she killed Archie - who had previously been the show's main antagonist prior to the character's death and murder storyline.
