The 68-year-old Bogner, who was only appointed last November but whose position has been under fire in recent weeks from the German media, admitted that he needed treatment for an intestinal illness but that it would not affect his role leading the Bavarian city's bid to become the first city to host both the Summer and Winter Olympics, he told insidethegames.

"I must come to terms with it and talk to the doctors," he said at the Sponsors Sports Venue Summit at the Allianz Arena here today.

"It is a serious thing, I cannot delay treatment."

The condition has been known about for more than two year and Bogner claimed that he would be able to carry on in his present role and continue to travel to promote it.

"It has been a dream of mine [to bring the Winter Olympics to Munich] ever since I took part in the Games myself," said Bogner, who competed for Germany at the 1960 Olympics in Squaw Valley.

"So I shall do my very best."

Bogner insisted that he would be in Acapulco next month when Munich, along with rivals Annecy and Pyeongchang, will be able to give the first international presentation of their bid to the Association of National Olympic Committees.

"We have the opportunity finally to talk to our clients," Bogner told insidethegames.

"We look forward to the experience.

"We have something special planned but we shall leave it as a surprise to our audience."
