WASHINGTON, Aug 12 (Reuters) - Former vice presidential candidate Sarah Palin will not speak at the U.S. Republican nominating convention in Tampa later this month, she said in statement on Sunday.

"This year is a good opportunity for other voices to speak at the convention and I'm excited to hear them," Palin, who was Senator John McCain's running mate in the 2008 election, said in a statement on Gretawire, the blog of Fox News's Greta Van Susteren.
