Over the years, EastEnders became well-known for characters returning after lengthy absences.
The likes of Martin Fowler, Ben Mitchell and Kathy Beale all spent several years off screen before coming back to the soap, but Peggy Mitchell is one of few to make multiple returns.
The iconic character, played by Barbara Windsor, shocked many viewers with her comeback.
