Mixed martial arts fighter Conor McGregor has announced he is quitting the race to become the Irish president.

The former MMA fighter had been due to address meetings of Dublin City Council and Kildare County Council later on Monday in an attempt to get onto the ballot paper for October's election.

To be eligible to run, a candidate must be nominated either by 20 members of the Irish parliament or four local authorities. They must also be an Irish citizen over the age of 35.

The sportsman announced his decision in a post on social media.

'Following careful reflection, and after consulting with my family, I am withdrawing my candidacy from this presidential race,' he wrote.
