The head of Brazil's football federation, Ricardo Teixeira, has stepped down from his post, days after taking sick leave.

He also resigned from the 2014 World Cup organizing committee.

Mr Teixeira, who led the federation for 23 years, had come under pressure over corruption allegations, which he has denied.

He has been investigated on suspicion of crimes including tax evasion but has never been convicted of any offence, BBC reported.
