Athletes found guilty of using steroids could face life bans and fines of up to $1 million (£700,000) under new anti-doping proposals put forward by the International Olympic Committee (IOC).

A package of proposed drug sanctions, including a precise definition of doping, has been drawn up by a special IOC panel and will be presented to representatives of 35 international federations in Switzerland tomorrow. The IOC want all federations to endorse a single medical code.
