Liberal MP says memo leak 'no big deal'

A Liberal MP has downplayed the leaking of a confidential federal government memo, saying it's "not a big deal".

The memo advising ministers to say things are going "exceptionally well" is a widely distributed daily document that summarises media articles, Parliamentary Secretary Steve Ciobo says.

"This ain't the budget papers leaked before the budget - this is an email that's distributed far and wide," he told ABC Radio on Wednesday.
