Burkina Faso's Salif Diallo, an ex-ally of ousted President Blaise Compaore, was chosen head of the national assembly, becoming the West African nation's second most powerful person after the president.
In a speech to parliament he called on members of assembly to fight against "the scourge of corruption [and] nepotism."
The 58-year-old was backed by 78 out of 127 lawmakers, just a day after Roch Marc Christian Kabore was sworn in as the country’s first new leader in almost three decades.
The two men were among the founders of the People's Movement for Progress (MPP) Party, which collected most of the votes last month in Burkina Faso’s first democratic elections in years.
They also used to be close allies of Compaore, who was forced to resign by a huge nationwide uprising in October 2014 after his attempt to change the constitution to extend his 27 years in power.
After serving in many government positions over the course of some two decades Diallo became one of the leading figures of the opposition along with Kabore.
Experts say MPP’s historic victory could bring together Compaore backers and the supporters of the 2014 uprising.
