MADRID (Reuters) - Spain’s caretaker prime minister, Mariano Rajoy, said on Sunday his center-right People’s Party (PP) had won a parliamentary election and therefore claimed the right to govern.

The PP won 137 seats, up from 123 in a previous election in December, but short of the 176 needed for an outright majority.
