Egypt hosted the event last year in Cairo - when it was moved from Minsk to due mass civil unrest in Belarus - and this year the nation has taken the place of China, with these World Championships first planned in Xiamen after the city lost out on the 2020 event over the COVID-19 crisis.

China's strict anti-virus rules mean that Xiamen could not play host this year either, but athletes from the country are due to compete.

The UIPM expects 170 athletes from 35 countries to challenge for world titles.

Competition is due to begin tomorrow with the men's relay.

The women's relay is scheduled the next day, before individual men's and women's competition unfolds over five days.

A mixed relay should bring the curtain down on the event a week tomorrow (July 31).

New men's and women's relay champions will be crowned as Russian and Belarusian athletes are banned over the war in Ukraine.

A Russian Modern Pentathlon Federation team - competing as such with the nation's flag and name banned as part of anti-doping sanctions imposed on the country - won the men's relay in 2021.

Belarus won the women's relay.

Anastasiya Prokopenko from Belarus also cannot defend her individual women's title.

Hungary's Ádám Marosi will not be defending the men's title either, although that is because he was not selected.

Reigning Olympic champion Joe Choong of Britain headlines a men's field also containing home hope Ahmed Elgendy and South Korea's Jun Woong-tae.

Elodie Clouvel from France, the reigning World Cup champion and an Olympic silver medallist, is in a women's field lacking current Olympic champion Kate French of Britain.

Hungary's Michelle Gulyás - a bronze medallist last year, one place behind Clouvel - is one to watch, so too 2019 world silver medallist Elena Micheli from Italy.
