As Grokan already pointed out, you're 'conflating Islamic extremists with the Muslim population as a whole.' (Grokan, 2012, p11) (Writing tons of essays, this amused me for some reason, stupid Harvard referencing system)
The issue at hand here is corruption and tampering with the electoral process. That's not something exclusive to muslims or sharia law. This whole line of argument started because of the claim that Sharia law is taking over Britain which was patently false, and remains false. Nothing you have posted has backed up your case, it merely demonstrates an underlying fear or hatred of Muslims.
