Delecour let his co-driver drive during the Power Stage
I think FIA ban changes between driver and co-driver after P.Solberg let C.Paterson to drive the Sweden's 2011 power stage.
Nope, what the new rule says is that, both, driver and co-driver must have a valid driving license all through the rally. Up to that moment, what the rule said was that the person driving had to have a valid driving license and a valid rally driver license and now both of them have to have them.
All WRC co-drivers must have a rally driver license since some time already. The idea is that they should be able to drive the car in case something happens that makes it necessary.
