During the latter part of his career, Sharon was investigated for alleged involvement in a number of financial scandals, in particular, the Greek Island Affair and irregularities of fundraising during the 1999 election campaign. In the Greek Island Affair, Sharon was accused of promising (during his term as Foreign Minister) to help Israeli businessman David Appel in his development project on a Greek island in exchange for large consultancy payments to Sharon's son Gilad. The charges were later dropped due to lack of evidence. In the 1999 election fundraising scandal, Sharon was not charged with any wrongdoing, but his son Omri, a Knesset member at the time, was charged and sentenced in 2006 to nine months in prison.
