To answer the question - no, I don't think either group has anything to worry about in this case. The Ayatolla was very careful to blame the British Government and was hoping to deflect some or all of the antagonism that the ordinary Iranians were feeling, from their own government towards the infidels in the west. I doubt in this instance it will work, the Iranians are far better educated these days and a lot more savvy.
The irony is that in all probability Ahmenadinejad has actually won the election fair and square but with a much reduced majority which might have weakened his position, the powers that be decided that he must have an appearance of being the popular choice so they rigged it for him. What goes round comes round.
