He was director of a company fined twice in Hungary for deceiving its clients and he has been accused of having violent encounters with two of his friends.
Sharpe's resignation comes on the heels of another controversy surrounding fellow party member, Eric Lucassen.
Last week, former neighbors of Lucassen appeared on Dutch television saying he had intimidated and threatened them.
Even more damaging, it was discovered that he had been convicted of sexual abuse in 2002 while serving in the army.
However, these disclosures did not lead to Lucassen to step down from his parliamentary post.
He remains a Freedom Party MP, albeit with a reduced portfolio.
Lucassen had reportedly kept quiet about his past criminal record during his selection process as a lawmaker.
The position of Lucassen is crucial for the Dutch minority government which is propped up by Wilders' party to give it a slim one-vote majority in parliament.
