Jevans, who heads the Organising Committee for Rugby World Cup 2015, will speak during a session entitled "Winning Bids and Delivering Outstanding Rugby Events", that will examine the issues and challenges of bidding for and staging major sporting events.

Jevans will be joined by Varadkar, who is also a member of the Foundation Board of the World Anti-Doping Agency (WADA).

He will outline why Governments back major sports events and how to maximise the potential socio-economic benefits that hosting the world's most prestigious events can deliver.
