An investigative commission in Brazil says it has found evidence that the ex-president Juscelino Kubitschek was murdered by the 1970s military regime, BBC News reported.

The Sao Paulo truth commission, a group of councillors from the city's assembly, is due to present a full report into the case on Tuesday, December 10.

The proof of the alleged conspiracy was found after analysing more than 90 pieces of evidence, the group says. At the time, the former president had just regained his political rights.

Kubitschek, who famously relocated Brazil's capital from Rio de Janeiro to the especially designed Brasilia, died on 22 August 1976 following a car accident on a motorway between Rio and Sao Paulo.
