Bolivian opposition senator Jeanine Áñez has assumed the interim presidency of the South American country following Evo Morales’s resignation.

Ms Áñez said she was next in line under the constitution and vowed to hold elections soon.

Her appointment was endorsed by Bolivia’s Constitutional Court.

Lawmakers from Mr Morales’s party boycotted the session, and the former president branded Ms Áñez “a coup-mongering right-wing senator”.
