Operation Transformation's 24 finalists were photographed earlier today in Santry Sportslink with the show's presenter Kathryn Thomas and RTÉ Radio One's John Murray.

Also taking part in the shoot were OT contributors Karl Henry (fitness expert), Dr Eva Orsmond (nutrition expert) and Dr Eddie Murphy, a Principle Clinical Psychologist with the HSE.

Operation Transformation is returning to our screens in January for a fifth series on RTÉ One.

The John Murray show is the radio home for the series and there will be extra content on RTÉ.ie.

Earlier today, The John Murray Show did a live broadcast from Santry Sportslink in which the final 24 applicants gathered to be assessed.

Murray spoke to the potential leaders about their personal stories, why they think they have what it takes to be a leader on the show and how their weight has affected their lives.

Next week, the five leaders selected to participate on the show will be unveiled live on The John Murray show by Kathryn Thomas.
