Former ACT opposition leader Zed Seselja is facing increasing pressure from government MLAs to quit the Legislative Assembly.

In the Assembly on Tuesday, the government said the opposition should demand Mr Seselja's resignation from his committee roles following his triumph over Senator Gary Humphries in the Canberra Liberals preselection contest.

Attorney-General Simon Corbell said Mr Seselja should step down as chairman of the standing committee on public accounts, in preparation for his departure from the Legislative Assembly.

Mr Seselja has not set a date for his resignation but said this week it would be ''well before'' the beginning of the official federal election campaign.

On Tuesday, new Opposition Leader Jeremy Hanson told the Assembly he wanted Canberra Liberals education spokesman Steve Doszpot to replace him on the standing committee on justice and community safety.

Mr Corbell said Mr Hanson's motion was ''just part of the transition in the Canberra Liberal Party'' and there was still ''clearly unfinished business'' before calling for Mr Seselja's removal from the public accounts committee.

Mr Corbell said on Tuesday the government did not believe Mr Seselja should continue in committee roles when he was already ''in the departure lounge''.

''Why is [Mr Hanson] allowing Mr Seselja to continue in the Assembly when he will very soon be actively campaigning for the Senate?'' Mr Corbell said.

The Attorney-General's comments follow Chief Minister Katy Gallagher's calls on Monday for Mr Seselja to resign from the Assembly as soon as possible.

She said it was not appropriate for the former opposition leader to continue to draw an MLA's salary when his priority was to campaign for the Senate.
