Ricky Martin slams Donald Trump

Singer Ricky Martin has criticised businessman Donald Trump, who kicked off his 2016 presidential campaign by making racist remarks about Mexico during an event.

"There's much hatred and ignorance in your heart @realDonaldTrump," Martin, 43, posted on Twitter.

His tweet comes after Univision announced it would no longer be televising Trump's Miss USA pageant on July 12 and following Colombian singer J Balvin's decision to opt out of performing during the pageant.

Trump had said that Mexico is sending the US "people that have lots of problems... They're bringing drugs. They're bringing crime.. They're rapists.
