Oh dear... Ali's only gone and lost the Rex Factor time machine during another of his fact finding trips through history. He's got all these wonderful tales to help Graham decide which Kings and Queens have the Rex Factor but they're no good stuck in the past. Fortunately Graham knows quite a bit about monarchs. If you can help him to jog Ali's memory, there's a good chance Ali might remember where he parked the time machine!
