A Malaysian court on Wednesday sentenced an opposition lawmaker to jail for revealing confidential bank details in a 2012 graft scandal, a potential blow on the opposition ahead of national polls that must be held by August. The outlook for re-election is still promising for Prime Minister Najib Razak, who is arguably in his strongest position since his narrow victory in the 2013 ballot, with the economy picking up, according to Bloomberg. Malaysia’s opposition alliance has named former premier Mahathir Mohamad as its prime ministerial candidate for this year’s general election, although the 92-year-old authoritarian faces an uphill task.
