The next presidential election is due to be held in 2016. Under the constitution, Mr Aquino will not be permitted to stand for re-election, although it is possible that his supporters will attempt to revise the constitution before then to allow the president to serve again. Elections will be held in May 2013 for one-half of the seats in the Senate and the entire lower house. The congressional elections will provide Mr Aquino and the LP with an opportunity to strengthen their position in the legislature. As Mr Aquino will still have three more years to serve as president by then, he will continue to benefit from all the possibilities for patronage that his office provides.
