Derek, played by Jamie Foreman, will be killed off in an upcoming storyline - but details of how he dies are being kept firmly under wraps by show bosses.
Cast and crew have been busy filming Derek's funeral episode in recent days, and new pictures have now been revealed offering a glimpse at the scenes in store.
Perhaps surprisingly given the animosity between them, Derek's son Joey seems to be one of the characters most affected by his father's passing. Joey's sister Alice is seen comforting him as he breaks down outside the church.
Foreman joined EastEnders as Derek late last year and his departure from the soap was confirmed last month.
Although Derek's death has not been officially confirmed as a murder, Max Branning has emerged as the bookies' favourite to kill him off.
