We reported earlier that the Nigerian senate has voted to reduce the lower age limit of the president.

This is part of a series of amendments to the country's constitution.

Nigeria's upper house of parliament has voted to weaken the power of the presidency and strengthen the legislature.

Members of the Senate approved a series of amendments to the country's constitution - including imposing time limits on key presidential decisions such as nominating ministers and proposing federal budgets.

If approved by the lower house and signed by President Mohammadu Buhari, it would be only the second time the 1999 constitution has been changed.

The lower house is set to vote on the amendments later this week.
