Following His Royal Highness’ address, IAAF President Sebastian Coe delivered an official welcome on behalf of Athletics’ world governing body.
A record 2038 athletes will compete at the IAAF’s flagship event, which runs through to 13 August.
“The opening night of a world championship is always exciting and I would like to salute the legions of people who create the stage for our athletes to captures the hearts and imagination of fans all over the world,” said Sebastian Coe.
The programme included performances by the renowned British soul singer Rebecca Ferguson who will sing the national anthem and perform her hit song, “Glitter and Gold”, and The Games Maker Choir, formed by volunteers who participated in the London 2012 Olympic and Paralympic Games, performed “One Day Like This’ by the artist Elbow, as a tribute to the legacy of the volunteers of those games and to those who will be volunteering at the IAAF World Championships London 2017.
The pre-show began at 6pm with a reallocation ceremony for five 4x400m relay teams and two 400m runners whose finishes at the 2009, 2011 and 2013 World Championships have been upgraded following the disqualification of the results of the original medallists after their sanction for anti-doping rule violations.
Competition on the opening day of the IAAF World Championships London 2017 began with the preliminary round of the men's 100m at 7pm and concluded with the final of the men's 10,000m, which double world and Olympic champion Mo Farah of Great Britain won.
