MANILA (Reuters) - Rodrigo Duterte was sworn in as the Philippines' 16th president on Thursday, capping the unlikely journey of a provincial city mayor whose brash man-of-the-people style and pledges to crush crime swamped establishment rivals in last month's election.

After making his pledge at the presidential palace in Manila, with one hand on the Bible, Duterte delivered a speech in which he promised a "relentless" and "sustained" fight against corruption, criminality and illegal drugs.
