LONDON (AFP) -- British Prime Minister Gordon Brown's ruling Labor Party have slumped to their lowest poll score against the main opposition Conservatives for 25 years, according to a survey published Sunday.

A YouGov survey for The Sunday Times put Labor on 27 percent, its lowest rating since 1983, while the Conservatives scored 43 percent.
If a general election were to take place now, the poll scores would translate into a landslide majority for the Conservatives.
Brown's personal approval rating has dropped to its lowest since he succeeded Tony Blair as prime minister in June, the survey showed.
It was carried out following Wednesday's budget and revealed deep-seated concerns among British voters about the economy, with 83 percent saying they believed it will grow more slowly over the next 12 months or enter a period of recession.
Alistair Darling, whom Brown appointed Chancellor of the Exchequer, or finance minister, to replace him, gained the support of just 22 percent of respondents for the way he was doing his job.
A majority of the 2,300 people polled said Darling's budget raised taxes but failed to tackle issues such as climate change.
