Officials from the sport's governing body said they feel the election did not respect the CBDA constitution or FINA rules.

Cagnoni, who was running on a platform of "innovation and transparency", gained 64 of the 96 votes cast.

Nearest challenger Cyro Delgado garnered 26 votes, while Jefferson Borges received only three.

According to the CBDA, two ballots were blank and one was annulled.

Cagnoni, the Paulista Aquatic Federation President, will become the CBDA’s first new leader since 1988.

It follows predecessor Coaracy Nunes, a member of the FINA Bureau, being arrested earlier this year as part of an inquiry into the alleged misuse of public funds.

However, FINA has told the CBDA that it will not recognise the results of the elections. 

Globo.com has obtained a screenshot of an official FINA memo sent to Gustavo Licks, who was appointed interim head of the CBDA, confirming as such on the eve of the elections.

"We would like to reconfirm that FINA will not recognise the elections of the Brazilian Swimming Federation on June 9, 2017 due to the fact that the elections do not respect the CBDA Constitution and FINA rules," the memo, which is signed by FINA executive director Cornel Marculescu, reads. 

Nunes was arrested in April along with CBDA financial director Sergio Ribeiro and water polo technical coordinator Ricardo Cabral.

Each are accused of "over-billing, diverting public funds and embezzlement".

The arrests specifically relate to the alleged misuse of around BRL$40 million (£10 million/$13 million/€12 million).

Nunes had already been removed from his post at the head of the governing body in October following an investigation by the Federal Police and Public Ministry.

The developments within the CBDA prompted Federal Deputy Arnaldo Jordy to call for a Permanent Commission of Inquiry to be set up to probe the use of public funds by the Brazilian sports federations.

Jordy made the suggestion at a public hearing, held to discuss the ongoing scandal within the CBDA.

Cagnoni was supported in his campaign by Luis Fernando Coelho de Oliveira.

Delgado, a 4x200 metres freestyle bronze medallist at the Moscow 1980 Olympic Games, was running on a platform called New Face alongside Ricardo Luis Barbosa de Lima.

The third Presidential candidate Borges currently serves as the head of the Mato Grosso do Sul Aquatic Federation.

Borges’ platform was titled "New Directions" and he was being supported by Marcelo Falcao.

Both Borges and Falcao are FINA referees and were selected by the governing body to officiate at the Rio 2016 Olympics.

The election was pushed back amid confusion over the Presidency of the CBDA’s five-seat Athletes’ Commission and the election voting rights that go with the position.  

In March, the CBDA named London 2012 400m medley silver medallist Thiago Pereira as the head of its Athletes’ Commission.

But amid the fallout from the corruption allegations against the CBDA, a judge stated that the national governing body must allow athletes to vote on their own President.

Two-time Olympian Leonardo de Deus was eventually selected as President and had a vote in the process.
