Depends on the year. Early Champion lawnmowers were produced for Focus DIY by Lawn-King, who also produced badged mowers for Homebase (Sovereign) as well as many other budget retailers.
It's possible that the latest range (within the last 2 years) have come out of the same Chinese factory as the current crop of Champion mowers, but whether it's a Champion or a challenge mower of the latest type you're still not going to get parts for it- unless it's engine parts you're after and it's fitted with a Briggs engine.
