New Brazilian Sports Minister Leonardo Picciani has insisted Rio 2016 will be an "absolute success" despite the political instability that has seen him become the third man to serve in his position in the last six weeks.

Picciani, a member of the centre-right Brazilian Democratic Movement Party (PMDB), was appointed as part of a Government shake-up by interim President Michel Temer after the suspension of Dilma Rousseff this week for 180 days pending an ongoing impeachment trial.

A former Congressman who voted against Rousseff being forced from office, Picciani replaces Ricardo Leyser, who had himself served just six weeks in the role after taking over from George Hilton in March.

"Construction and preparations for the Games are advancing well, respecting the timeline, and I'm absolutely convinced we'll have no problem," the 36-year-old public news service Agencia Brasil.

"Brazil's Olympic Games will be an absolute success and will undoubtedly boost the country's image on the international stage, as well as leave an important legacy for the benefit of the population."

This comes as Rio 2016 and Government officials repeatedly insist that the political instability will have no impact on the Games.

Frequent changes in personnel are far from ideal, however, particularly because Leyser was such an experienced sporting official who played a key organising role when Rio de Janeiro hosted the Pan American Games in 2007.

Picciani, who becomes the fifth Sports Minister since Rio was awarded the Games in 2009, has had no official sporting role before, but is known to be a sports fan.

Leyser, a member of the Communist Party Brazil, was seen as a close ally of Rousseff, so was likely removed for political reasons.

He is set to still play an organising role, however.

Rousseff was forced to stand-down following a Senate vote this week for "fiscal irresponsibility" after she allegedly tried to manipulate budget gaps during the 2014 election, but has denied any wrongdoing.

Temer - despite being, as Rousseff's former vice-president, accused of the same claims - took over and is now set to be in charge for the duration of the Olympic and Paralympic Gamesm, and to thus officially declare them open.

He has already met with Rio de Janeiro Mayor Eduardo Paes and is claiming to be fully supporting of the Games and all required preparatory work.
