Former allies of Burkina Faso's longtime president have created their own political party in the latest sign of growing opposition to his rule.

Earlier this month, the ruling party suffered an unprecedented crisis when dozens of its members deserted.

They said they were now siding with opposition leaders to stop any attempt to amend the constitution and set up a senate that many see as a chamber that will facilitate President Blaise Compaore's contest for another term in 2015.

Last week, thousands of protesters marched in Ouagadougou along with opposition leaders joined by dissidents of the ruling party.

The new party unveiled Saturday will be known as the Movement for the People and Progress, or MPP. Its leader is a former parliamentary speaker. Compaore has been in power since 1987.
