Earlier this month, news broke that Victorian Labor senator Kimberley Kitching had died suddenly at the age of 52.
"The Labor family is in shock tonight at the tragic news that our friend and colleague Senator Kimberley Kitching has died suddenly in Melbourne," Labor leader Anthony Albanese said at the time.
In the days since, a string of allegations have come to light claiming Kitching - who died from a suspected heart attack - was bullied and ostracised by senior female members of the Labor party.
Reports also emerged that Kitching allegedly raised her bullying before her death on Thursday, March 10.
On Monday, while farewelling his wife at a funeral service at Melbourne's St Patrick's Cathedral, Kitching's husband, Andrew Landeryou, further shed light on the "unpleasantness " his wife experienced in parliament.
"They know what they saw with their own eyes," he said during the eulogy.
"Of course there’s a lot I could say about the unpleasantness of a cantankerous cabal, not all of them in parliament, that was aimed at Kimba.
"I hope it’s sufficient to say she deserved so much better. Her friends and ferociously loyal staff are angry about how she was treated. The intensity of it did baffle and hurt her."
With questions remaining about Kitching's treatment in parliament, here's what those involved have said.
What are the bullying accusations?
Allegations about bullying within the Labor party quickly came to light following Senator Kitching's death.
An article by The Australian reported on claims the 52-year-old was bullied and ostracised by senior female members of her party, including Senators Penny Wong, Katy Gallagher and Kristina Keneally.
The ABC have also reported that Kitching told a parliament-employed workplace trainer she was being bullied by colleagues, before her death.
A number of her employees reportedly told the publication she raised the bullying when she was undergoing workplace education on November 5 last year, telling colleagues she allegedly asked the trainer, "What are you going to do about the fact that I am being bullied?"
However, according to the publication, it's not known whether she made any formal steps towards an official complaint.

Following the bullying allegations, Senators Penny Wong, Katy Gallagher and Kristina Keneally released a joint statement on Friday denying the claims.
In the statement, the senators explained they initially declined to comment on the allegations "out of respect" for Kitching and her family.
