Angola

In Angola the parliament has just approved a new constitution which abolishes direct presidential elections - the leader of the party with the parliamentary majority, automatically becomes head of state.

But the opposition isn't happy about this.

Not least because although the new constitution only allows a president to serve two five-year terms, it's expected to come into force in 2012.

This means that the current President, Eduardo dos Santos, could remain in office until 2022.

On the line from Luanda, the main opposition party, Unita's president, Isias Samakuva, has been telling Lewis Machipisa about his misgivings.
