Spain's Prime Minister Mariano Rajoy said Wednesday he will submit the eurozone deal on Greece's debts to parliament to ensure support for his country's multi-billion dollar contribution.

"Although this procedure is not obligatory in our country, it is my intention to bring the deal before parliament to be debated," said Rajoy, who estimates Spain will contribute about 12 percent of a package worth up to 86 billion euros ($95 billion) overall.
