LISBON (Reuters) - Portugal's centre-right Democratic Alliance (AD) has extended its lead according to a new opinion poll ahead of Sunday's general election, but it still looks like falling far short of the parliamentary majority needed to form a stable government.
The survey by pollster Lisbon's Catholic University, released by broadcaster RTP late on Thursday, put support for Prime Minister Luis Montenegro's AD at 34%, up from 32% in the same poll a week ago.
