The president of Democratic Republic of Congo, Joseph Kabila, has announced the formation of a new government which includes several opposition members.
A senior member of opposition party the Movement for the Liberation of Congo has been named a vice prime minister.
Several other former opponents have also been given posts.
The unity government comes amid speculation that Mr Kabila, in power since 2001, may try to change the constitution to run for a third term.
Analysts say the inclusion of opposition members and former opponents in his latest administration may be an attempt to broaden his support and divide an already weakened opposition.
They say this may be in preparation for constitutional changes or a delay to elections due in 2016.
Evariste Boshab, leader of the governing People's Party for Reconstruction and Democracy and an outspoken advocate of constitutional change, has also been named a vice prime minister.
The new government is made up of 47 ministers and vice ministers, replacing the previous 36-strong administration.
Prime Minister Augustin Matata Ponyo, who has headed the outgoing government since April 2012, retains his post.
Mr Kabila promised to form a unity government last year after a national dialogue with opposition and civil society groups.
Donors and investors say the delay has fostered uncertainty and stalled reform in the vast country which is rich in minerals, Reuters news agency reports.
