Dermot O'Leary

O'Leary's X Factor work is worth revisiting for the host's position between a nervous performer, a powerful judging panel and a tightly timed live show. His geniality and willingness to offer reassurance gave that machinery a recognisable human presence. This is a judgement about his presenting, not an endorsement of every aspect of the programme: he has acknowledged that some participants did not have the best experience.
