Michel Temer is a president few Brazilians want, replacing a leader few saw fit to stay.

The Senate's dismissal on Wednesday of Dilma Rousseff, the least popular president since Brazil returned to democracy three decades ago, handed power to the vice president, who is almost as unpopular.

For much of his five decades in politics, the soft-spoken Temer has worked in the shadows, building alliances within his fragmented Brazilian Democratic Movement Party (PMDB) and rising to become one of the leading deal-makers in Brazil's Congress.
