In late February 2005, Mubarak announced a reform of the presidential election law, paving the way for multi-candidate polls for the first time since the 1952 movement. However, the new law placed restrictions on the candidates, and led to Mubarak's easy re-election victory. Voter turnout was less than 25%. Election observers also alleged government interference in the election process. After the election, Mubarak imprisoned Ayman Nour, the runner-up.
