The 64-year-old woman who swam from Cuba to Florida without the aid of a shark cage is set to answer her critics over whether she cheated.

Diana Nyad has been hailed by many across the United States, with President Barack Obama saying her achievement showed people they should "never give up on your dreams".

ITV News' Lucrezia Millarini reports:

Diana is proud of what she and her team accomplished last week, and she is committed to complete transparency.

Her progress was tracked by a satellite and questions over her feat were raised after it emerged that for one seven-hour period, Nyad apparently did not stop to drink or eat.
