This year's Poppy Appeal was launched with a concert held for armed forces' families at RAF Northolt, featuring The Saturdays and Britain's Got Talent finalists Luminites and The Poppy Girls.
The Appeal is organised by The Royal British Legion and is this year focused on the families of Army, Royal Air Force and Navy personnel. The Royal British Legion hopes to raise £37 million.
TV personality Gethin Jones hosted the concert, which also included a performance from Tich. The Poppy Girls sang the official appeal single, The Call (No Need to Say Goodbye).
George Shelley from Union J said: "It was amazing to launch the Poppy Appeal this year. Personally, the poppy means a lot to us, it's a symbol of pride.
"I have a brother serving in the Royal Marines, Josh's dad was in the Navy for ten years, and Jaymi's uncle was in the RAF and fought in the Falklands War."
