Democracy icon Aung San Suu Kyi has fallen ill while campaigning for Myanmar's upcoming by-elections and has suspended her extensive tour of the country a week ahead of the polls, her party said on Sunday. The National League for Democracy said Ms. Suu Kyi's personal physician advised taking the break after she fell ill with vomiting while campaigning in the Mergui archipelago in southernmost Myanmar. The doctor said her ill health was due to exhaustion and the hot weather. Released from house arrest in 2010, Ms. Suu Kyi has travelled thousands of kilometres by car, plane and boat to campaign around the country for her party.
