Siobhan Haughey – the grandniece of former Taoiseach Charles Haughey - has qualified for her second final at Tokyo 2020.

The Hong Kong athlete made history for her country on Wednesday when she won the nation's first Olympic swimming medal by taking silver in the 200m freestyle.

Haughey has followed up that achievement on Thursday by qualifying for the 100m freestyle final.

The 23-year-old won her semi-final in a time of 52.40, setting an Asian record in the process and the second fastest time in the two semi-final heats behind Olympic record holder Emma McKeon of Australia.

The 100m freestyle final will take place on Friday in which Haughey will take on competitors including Sweden's world record holder Sarah Sjostrom, McKeon and Australia's former world champion and triple Olympic relay gold medallist Cate Campbell.

Haughey is also due to compete in the women's 50m freestyle heats later on Friday.
