Brazil's PMDB party quits government's coalition

Pressure is growing on Brazil's embattled president, Dilma Rousseff, after the PMDB, the largest party in Brazil's ruling coalition, voted for an "immediate exit" from her government.

Ms Rousseff is fighting moves to impeach her, following allegations she manipulated accounts, to hide a growing deficit.

She has described attempts to oust her, as a coup.
