Operation Transformaiton presenter Kathryn Thomas has launched the search for new leaders for the show's upcoming seventh series.

Speaking on The John Murray Show with Miriam O'Callaghan this morning, Thomas said: “I am delighted to be presenting the seventh series of Operation Transformation. It’s such an inspiring series and really proves what people can achieve when they put their minds to it.

"Last year the five leaders inspired so many people as they worked to improve their lives and showed just what can be achieved with focus and the support of the Operation Transformation experts and the whole nation.”

Thomas was joined live in studio by the leaders from last years show; Deirdre Hosford, Monica Percy, Gavin Walker and Greg Starr, with Charlotte O'Connell joining them on-air via phone.

In other Op Trans news, after six successful series on the show, Dr Eva Orsmond has decided to leave the popular programme: “After a fantastic six years," she says, "I have reluctantly taken the decision to step down from Operation Transformation.

"I am engaged in developing several new projects in my clinics with a focus on childhood obesity, anti ageing and complete nutritional services. I am also in the process of completing my new book on weight loss which will be published by Gill McMillan in January 2014.

"It has been a pleasure to work with the OT team and all the leaders.”

RTÉ Television’s Head of Lifestyle, Grainne McAleer, added: “Dr Eva has been with Operation Transformation since the beginning and has been a very important part of the team.

"We are sorry to lose her but we thank her for her incredible work helping so many people in Ireland achieve a healthier lifestyle and we wish her all the very best for the future.”
