Embattled Brazilian President Michel Temer has said he will fight allegations that he endorsed the paying of hush money to an ex-politician jailed for corruption.

Mr Temer spoke during a national address in his first appearance since the Globo newspaper published a report claiming he was recorded supporting payments to former lower house speaker Eduardo Cunha.

In his speech, Mr Temer categorically denied the allegation and insisted he will stay in his job.
