The FINA Bureau also awarded Hungarian capital Budapest, which pulled out of the race for the 2024 Olympic and Paralympic Games earlier this year, the 2018 World Junior Synchronised Swimming Championships.

The four candidates for the two editions of the World Swimming Championships (25m), known as the World Short Course Championships, are also bidding to host the FINA World Aquatics Convention.

The host for each event will be allocated by the Bureau on July 17.

Several decisions were taken today by the FINA Bureau, which met prior to the FINA World Championships in Budapest, due to begin on Friday (July 14).

FINA approved the organisation of a World Water Polo Conference following the International Olympic Committee's (IOC) decision to cut the squad sizes from 13 to 11 for Tokyo 2020.

The worldwide governing body expressed its support for the IOC's decision to increase the number of swimming events in the Japanese capital.

A mixed 4x100m medley mixed relay was added to the swimming programme, along with additional men's 800m and women's 1,500m freestyle races, ensuring that male and females will be able to take part in the same number of events in the pool at the Games in the Japanese capital.

Swimming is now the largest sport at Tokyo 2020 with 49 medal events.

The Bureau also acknowledged the "excellent cooperation" with the Tokyo 2020 Organising Committee.

The World Water Polo Conference will be held at the end of this year, FINA said, "to discuss and propose new ways of enhancing the first Olympic team sport in the five continents".

Once proposals are finalised by the new Technical Water Polo Committee, which will be established at the Congress in Budapest on July 22, FINA will then call an Extraordinary Congress to validate the changes made.

FINA also approved the anti-doping educational programme.

It is claimed this will help to "raise awareness and information about anti-doping procedures among athletes and National Federations".

Reports were then given by the Organising Committees of next year's World Short Course Championships in Hangzhou in China and the FINA World Championships in Gwangju in 2019.

FINA's Congress will be dominated by the Presidential election, where incumbent Julio Maglione is being challenged by controversial European Swimming Federation (LEN) head Paolo Barelli.

The run-up to the vote on July 22 has been dominated by Barelli referring FINA vice-presidents Husain Al-Musallam and Dale Neuburger to the Court of Arbitration for Sport (CAS).

Barelli had appealed over alleged interference at last year's LEN elections, where he beat Dutchman Erik van Heijningen by 50 votes to retain his position as President. 

Barelli lost his appeal at CAS but is considering taking his case to the Swiss Federal Tribunal.

Delegates from Africa, Asia and Oceania were recently urged to vote to re-elect Maglione by the heads of the respective continental bodies.

The 81-year-old Maglione was only able to stand for a third term after he successfully proposed a motion abolishing age limits and relaxing term restrictions for the President of FINA in 2015.
