LISBON (Reuters) - Portugal's centre-left Socialist Party (PS) has extended its lead as the favourite to win the most votes in a snap general election on March 10, although it remains far from a parliamentary majority, an opinion poll showed on Tuesday.
There was also a strong jump in voting intentions for the third-placed far-right party Chega (Enough) that could be key to the wider right wing forming a government, according to the survey by Intercampus for newspapers Correio da Manha and Jornal de Negocios.
