Joe Swash was not amused when he arrived to take part in his third trial. When greeted by Ant and Dec he said: “I didn’t think I would be back this soon not after yesterday that’s a bit mean.”

Joined by Robert, they were told the rules. Both had to enter aseparate chamber and compete head to head to win food for their camp. They each had to climb to the bottom of their chamber where they were chained in leg irons, a waist belt and hand cuffs.

With six padlocks each, they had to find the six keys which were attached to stars at the bottom of the chamber, each key would unlock a padlock. The first celebrity to unlock all six padlocks and pull the lever at the top of the chamber would win a luxury meal for their camp, the losers would have to survive on rations.

Robert and Joe climbed into their chambers and as soon as the lid closed shut the chambers filled with water. As they both found the keys and unlocked the first three padlocks Ant and Dec informed that they that they were both neck and neck. As the water quickly filled the chambers Joe struggled with the fourth lock whilst Robert, rising to the top to get air, reached the sixth lock. Convinced that he had opened the final padlock Robert climbed to the top and pulled the lever but as he tried to climb out he was still attached to one of the handcuffs. “I’ve won,” he exclaimed.

But Dec informed him that he had not unlocked the final padlock and he would have to go back and retrieve the key. Finding what he believed was the correct key Robert was unable to open the padlock and said to the hosts that he had a ‘dodgy lock’. In the meantime Joe completed the trial. Robert, sure that the key in his hand was the correct one for the lock on his arm was left red-faced when it was proved he was trying to open it with the wrong key. One of the discarded keys at the bottom of the tank opened the padlock and freed the politician, the key is in hand had been used to open one of the other locks.

Still convinced he should have won he bantered with his opponent that he was cheated and Joe joked that “he should take it like a man”.
