Brazil has been rocked by dramatic new corruption allegations after a judge ordered investigations into eight cabinet ministers and scores of MPs, BBC reports. 

The list includes President Michel Temer's chief of staff, Rio de Janeiro's mayor during the Olympics and at least four former presidents.

They were named by employees of construction firm Odebrecht, which has admitted paying $1bn in bribes.

It is part of a three-year probe into graft at state oil company Petrobras.

All 108 people named on the list released by Supreme Court Judge Edson Fachin are suspected of involvement in a massive bribery and embezzlement operation that took money out of Petrobras and funnelled it into politicians' pockets and political party slush funds.
