Leederville's famous St Patrick's Day parade and festival has become the second major Perth event to be canned on Friday as concerns over coronavirus transmission grow.

On Friday morning the City of Vincent and St Patrick’s Day WA Inc confirmed they had cancelled the event in the "best interest of the community given current concerns around mass gatherings."

Up until late on Thursday evening the festival, which celebrates all things crustacean in the Peel region, was set to go ahead.
