MADRID, July 11 (Reuters) - Spanish opposition leader Alberto Nunez Feijoo, leader of the conservative People's Party (PP), won an ill-tempered televised debate on Monday night ahead of an election later this month, a poll published by El Mundo newspaper indicated on Tuesday. With Feijoo leading in polls before the July 23 election, the onus was on Prime Minister Pedro Sanchez, a Socialist, to go on the attack. About 54% of voters thought Feijoo won the debate compared to 46% for Sanchez, according to the Sigma Dos survey for El Mundo. It found that 22% of people who voted for the Socialists in the past election felt Feijoo had won the debate while only 6% of PP voters assigned the victory to Sanchez. The expectation is that the election at the height of the summer holiday season will also suffer from a lack of engagement.
