MPs prepare to debate a motion of confidence that looks likely to topple centre-right government

Portugal is bracing for its third snap general election in as many years as MPs prepare to debate a motion of confidence that looks set to topple the centre-right government and trigger a return to the polls in May.

Luís Montenegro, the prime minister, who heads the Democratic Alliance (AD) platform that has governed Portugal since its narrow victory in last year’s election, called the vote of confidence, which is due to take place on Tuesday, in response to growing questions over his family’s business activities.
