A UKIP AM will be questioned on Tuesday by the assembly’s standards committee about a racial slur she used to describe a Labour MP.
Michelle Brown was recorded generating the comment about Chuka Umunna in a telephone conversation with an adviser.
She has already accepted her language was “inappropriate” along with also has apologised.
If the committee recommends a sanction – which could range coming from a reprimand to a suspension – there would likely be an assembly vote on of which.
The cross-party standards of conduct committee will be considering a report on the matter written by the Standards Commissioner Sir Roderick Evans.
Ms Brown along with also UKIP Wales leader Neil Hamilton will give evidence to the committee.
If the commissioner has concluded Ms Brown broke the code of conduct governing AMs’ behaviour, the committee will then decide whether to recommend she will be sanctioned.
Ms Brown called the Labour MP a “coconut” during a conversation in May 2016 with her then senior adviser, Nigel Williams.
She was also recorded using an abusive remark about Tristram Hunt, who was then Labour MP for Stoke-on-Trent Central.
Mr Williams, who was her senior adviser for 12 months, was sacked by Ms Brown in May 2017.
The chair of the committee, Jayne Bryant, will not take part in proceedings on Tuesday because the group she belongs to within the Senedd, Labour, made the original complaint.
When the recording came to light in July 2017, Michelle Brown, a regional North Wales AM, said: “The point I was generating will be of which because of his considerable wealth along with also privilege, Chuka Umunna cannot possibly understand the difficulties along with also issues of which the average black person faces in of which country any more than I can, along with also I stand by of which assertion.
“I do however accept of which the language I used within the private conversation was inappropriate along with also I apologise to anyone of which has been offended by of which.
“As far as the language I used about Mr Hunt will be concerned, of which was a private conversation along with also I was using language of which friends along with also colleagues often do when chatting to each some other.”
The Labour assembly group called for Ms Brown to be suspended along with also referred the matter to the Standards Commissioner.
A Labour spokesman said Ms Brown had used “absolutely outrageous language” of which “lays bare the disgusting racism at the heart of UKIP”.
At the weekend, UKIP suspended Jo Marney, the girlfriend of its leader Henry Bolton, after she reportedly wrote racist messages about Meghan Markle.
