The Brazilian Olympic Committee's provisional ban has been partially lifted by the International Olympic Committee, enabling it to take part in sports meetings in Prague this week.

The ban was imposed earlier this month following the shock arrest of its former president and Rio 2016 chief Carlos Nuzman on charges of bribery and fraud.

At the time, Olympic bosses also suspended Nuzman's honorary IOC membership, withdrew him from the co-ordination commission overseeing Tokyo's preparations for the 2020 Games and stopped all payments due to COB. Those sanctions remain in place.

Since the IOC's initial response to the corruption allegations in Brazilian sport, the COB has held an extraordinary general assembly to confirm Nuzman's resignation and promote vice-president Paulo Wanderley Teixeira to the top job.

It also committed to a review of its governance structure and an investigation into its finances from 2008 to 2010 to make sure it is not involved in the allegations against Nuzman, who led the organisation for 22 years.

In a statement confirming the BOC will now be able to participate in this week's meetings in the Czech Republic, the IOC said: "There will be no decision about the final lifting of the provisional suspension of the COB until this process is finished."

Nuzman and Rio 2016's general director Leonardo Gryner were arrested last month, following raids of their homes and offices by the Brazilian authorities in September.

Those raids followed a tip-off from French prosecutors who have been investigating former world athletics boss Lamine Diack and his associates for the last two years - an inquiry that has already unearthed evidence of widespread corruption in global sport.

According to the Brazilian media, Nuzman has been accused of passing bribes from a wealthy Brazilian businessman to Diack in order to secure the support of African IOC members ahead of the 2009 vote which gave the Games to the South American city.

The 75-year-old Nuzman, who played basketball for Brazil in the 1964 Olympics, denies any wrongdoing.
