SIDON, Lebanon (Reuters) - The last time Lebanon held a parliamentary election, Youssef Sanjar enjoyed a paid flight home from Saudi Arabia to vote for Prime Minister Saad al-Hariri's party.

As an employee of the then thriving Saudi Oger construction company owned by the Hariri family, there was no question whom he would support. He helped with campaign logistics and his mother nagged neighbours in the southern Lebanese city of Sidon to make sure they voted.
