Biography
Together with Anthony McPartlin, Declan was part of the duo Ant & Dec. (PROSE: )

At some point in the early 1990s, he was locked in invisible space handcuffs with Ant. The duo encountered the Doctor, who they believed could free them from the handcuffs. (TV: )

Following the Vore invasion of Earth in 2005, Dec was reported alive while Ant had been reported missing and presumed dead. (PROSE: ) However, Ant was later revealed to be alive in 2011.

By 2011, Dec was still locked in the invisible handcuffs and hoped the Eleventh Doctor would be able to free him. When the TARDIS materialised in their home, Dec asked Dermot O'Leary if the Doctor had come back to free him, explaining that he had been locked in the handcuffs for 21 years by this point. Dermot, however, stated he was busy and left. Ant said he needed to go to the toilet, much to Dec's annoyance, as the handcuffs meant he would have to come with him. (TV: )
