U.S. real estate mogul Donald Trump has announced he won't run for president, abandoning a bid for the Republican nomination for next year's election.

Some opinion polls had once shown Trump leading the Republican field, which still lacks a clear front-runner.

Among the top hopefuls are former Massachusetts Governor Mitt Romney, former House Speaker Newt Gingrich, and former Minnesota Governor Tim Pawlenty.
