A charity Quidditch match? I love it!
I'm all for single-line paragraphs for effect, but you could stand to glue some of those sentences in the beginning together.
The scene in front of Wheezes might be funnier if you said exactly what Harry did to the poster. Changed it to say "For a Good Time, Call?"
"defiantly not a joke" I think you meant, "definitely not a joke." You've got a few run-on sentences in here. No biggie.
Oho! And Harry doesn't get to blame the politically overactive Miss Granger for this one! It is the bane of his existence, the Daily Prophet! Delightful.
Why would Dumbledore support Percy? Percy was all for complacency and obedience; Dumbledore was not.

You might want to mention how Fudge got reinstated as Minister. He'd been compelled to step down.
You mention Dumbledore as if he is still alive. You should amend this or mark it A/U.
Author\'s Response: Fixed the beginning and the spelling error thanks for pointing those out. Also changed story to AU. My idea is that Dumbles supported Percy because he thought there was the possiblity of controling him and to maintain the status quo.Thanks for this great review I really appreciate it. :)
