Angola’s President Jose Eduardo dos Santos will seek a new term with former state oil company head Manuel Vicente as his vice president in September polls, a source in the ruling MPLA said Saturday.

The southern African oil giant is expected to hold elections around September, and the run-up is being closely watched for signs of whether Dos Santos will seek a new term and whom the MPLA might pick to replace the long-ruling leader, in power since 1979, when he eventually steps down.
