Spain's centre-right People's Party will win Sunday's election with an absolute majority in parliament, according to an exit poll by public broadcaster RTVE.

The poll showed the PP taking 181 to 185 seats in the 350-seat lower house, or 43.5 percent of votes.

The Socialists were lagging with 30 percent of votes, and would take 115-119 seats, the exit poll said.
