Two Malaysian badminton players have been hit with career-ending bans of 20 and 15 years respectively after being found guilty of corruption and match-fixing, the sport's governing body said Wednesday.

The Badminton World Federation (BWF) said former world junior champion Zulfadli Zulkiffli, 25, was banned for 20 years and fined $25,000, while Tan Chun Seang, 31, was barred for 15 years and fined $15,000.

They were found guilty of breaching the BWF code of conduct in relation to “betting, wagering and irregular match results”, said a statement from the body.

A BWF ethics panel, which held hearings in February in Singapore into the case, found both players “engaged in corruption offences over a significant period and a significant number of tournaments” dating back to 2013.

Zulfadli committed more violations over a longer period and it was proven he had manipulated the results of four matches, the BWF said.

Norza Zakaria, president of the Badminton Association of Malaysia (BAM), said it was a “sad and shocking day for Malaysian badminton, to know a sport so close to our hearts has been tainted by match-fixing”.

“BAM has a zero tolerance policy towards match-fixing,” he said, adding programmes would be organised for those involved in the sport to counter such activities.

He said the punishment handed down to the pair, who played independently and were not affiliated with BAM, was “reasonable and appropriate considering the offence”.

BAM will now present a report on the incident to Malaysian anti-corruption authorities, who will consider whether to take action.

Their suspension began from January 12, the date on which both players were provisionally suspended by the BWF.

Tan was in Malaysia's squad for the prestigious Thomas Cup in 2010.

He was banned by the BAM from competing in Asian tournaments for two years after quitting the national team in 2011.

In 2011 Zulfadli beat current world champion Viktor Axelsen of Denmark to clinch the World Junior Championships.

Badminton has been hit by cheating scandals before.

At the 2012 Olympics, eight women's doubles players were disqualified for trying to lose group games to gain an easier quarter-final draw.

And in 2014 the BWF asked police to investigate claims by two Danish players, Hans-Kristian Vittinghus and Kim Astrup, that they were approached by a Malaysian man to throw matches.
