Peru's Congress voted against the ouster of President Martin Vizcarra on Friday in an impeachment trial that heightened political tensions in the world's second-largest copper producer.

After a 10-hour debate, during which Vizcarra gave a brief statement at the beginning, only 32 legislators voted for his dismissal, while 78 voted against and 15 abstained. 

The opposition-dominated Congress vote fell short of the 87 out of 130 vote threshold for ousting the centrist leader on grounds of "moral incapacity" over alleged links to a case of irregular government contracts with a little-known singer.
