Oliver Peterson: Australian correspondent on former deputy prime minister Barnaby Joyce being filmed on Canberra footpath - Heather du Plessis-Allan Drive

Barnaby Joyce has admitted to making 'a mistake', after a compromising video of him on a Canberra street surfaced.

In the video, Joyce had fallen on the ground off a planter box and was swearing into his phone after  a long parliamentary sitting day.

The former deputy prime minister has blamed the mix of alcohol and prescription medication for his actions last Friday.

Australian correspondent Oliver Peterson says several people have spoken up to defend Joyce after the incident.
