AFA cancels Frydenberg lunch ahead of swearing in

At a press conference earlier this week, Mr Turnbull said the new-look cabinet would be unveiled on Monday.

In a release to media, the AFA said "it is with regret that we announce the lunch event in Melbourne with the Assistant Treasurer has been cancelled".

"With the make-up of Prime Minister Turnbull's Ministry likely to remain in doubt until the end of this week, the AFA has been informed that all party members have been instructed to clear their schedules for a swearing-in ceremony in Canberra on Monday 21 September."

An AFA spokesperson said it was unclear whether the event would be rescheduled.

Meanwhile, the government has maintained its commitment to the FSI process.
