Here's Channel 9's report
9NEWS understands resigning Liberal MP Ann Sudmalis has accepted an offer from the Prime Minister to be seconded to the United Nations in New York.
It is likely today will be her last day in parliament until she departs.
9NEWS revealed the post was also offered to Julia Banks, who is quitting at the next election citing bullying and intimidation, but she rejected it.
The annual bipartisan trip involves one MP from both the Liberal and Labor parties and starts in September, concluding in December.
The delegates normally work with the Australian Mission to the United Nations, and conduct speaking engagements.
It's understood Labor veteran Jenny Macklin will be the Labor representative for the next three months.
Ms Sudmalis' decision to accept the offer, will see her away from Parliament until the end of the year.
