Brazil's tourism minister quits, delivering a potentially fatal blow to an already rattled presidency.
Henrique Eduardo Alves resigned on Monday, March 28.
The move comes as President Dilma Rousseff's government deals with sweeping accusations of corruption.
Rousseff herself faces an impeachment bid.
Alves belongs to the Democratic Movement Party, a large centrist party that has been aligned with Rousseff's Worker's Party.
However, after Alves quit, the party voted on Tuesday to abandon the Worker's Party.
Without the Democratic Movement Party, analysts say Rousseff's chances of surviving an impeachment vote significantly diminish.
The party has 69 sitting Members of Parliament.
Rousseff needs the support of at least a third of the 513 MPs to survive the vote.
Her Worker's Party has 58 sitting MPs.
In addition, her support from the Progressive Party and the Social Democratic Party hangs in the balance.
Those two parties have a combined total of 81 sitting MPs.
