| The Court of Arbitration of Sport (CAS) on Tuesday upheld the 
				International Paralympic Committee (IPC) ban on Russia competing 
				at the Sept. 7-18 event.
 "It's probably the right choice if they've got evidence that 
				most of the athletes are on a doping program," the six-times 
				Olympic champion told British media on Thursday.
 
 "It's a bold step by the IPC and definitely the right one if 
				they've got evidence.
 
 "Over the last few years I've started to doubt people, which you 
				never want to do. You look at people's performances and think 
				'really?' and not 'wow'."
 
 The six-times wheelchair London marathon winner said the 
				drug-testing system was less stringent outside Britain.
 
 "The doping policy needs to be a bit more thorough throughout 
				disability sport. Not in the UK, because we're tested 
				constantly, but throughout championships," the 37-year-old 
				added.
 
 "We've seen athletes getting caught and if it's happening in the 
				mainstream, it's got to be happening in the Paralympics. When I 
				was at the European championships I did four events and got 
				tested once.
 
 "Maybe it's manpower or funding. A lot of nations are throwing 
				millions of pounds at medals and we want to deliver on a level 
				playing field."
