Brazil political crisis 'would worsen following defection'
A top Brazilian judge says a political crisis gripping Brazil will deepen if a major ally quits President Dilma Rousseff's governing coalition, as expected.
Supreme Court Justice Gilmar Mendes says Brazil will become harder to run if the Brazilian Democratic Movement Party confirms it is withdrawing its support for Ms Rousseff's troubled administration.
Mr Mendes recently blocked former Brazilian president Luiz Inacio Lula da Silva's nomination to a cabinet post due to ongoing corruption investigations, though that decision is under appeal. Ms Rousseff had sought to shore up her government by bringing in Mr Lula.
Mr Mendes was attending a three-day legal conference in Lisbon, Portugal, which began on Tuesday. About 50 people, mostly Brazilians, protested outside the event against moves to impeach Ms Rousseff amid a huge kickback scandal involving her Workers Party.
They called the impeachment an attempted coup and jeered Brazilian Senator Jose Serra, one of Ms Rousseff's opponents, as he entered the building.
"The government's support base will become even narrower, and the political crisis will obviously worsen" if the ally walks out, Mr Mendes told reporters.
Senator Aecio Neves, who narrowly lost to Ms Rousseff in the 2014 presidential run-off, is scheduled to speak at the conference on Thursday.
