Colleagues shield under-fire Labor MP Jags Krishnan from media

A group of WA Labor MPs have attempted to shield one of their own from answering questions from the media in extraordinary scenes outside state parliament.

Questions about the business dealings of Riverton MP Jags Krishnan and his disclosures to parliament about his debts have been growing since it emerged he was being sued in the United States over a million-dollar loan.

He has vowed to "vigorously defend" his position and launched a case for defamation in response.

Journalists tried to ask the second-term MP questions as he arrived at parliament on Wednesday but were blocked by a group of colleagues including Terry Healy and David Scaife.

Mr Healy stood between the under-pressure MP and the media at one stage.

"It's all getting sorted," Dr Krishnan said as upper house Labor MPs Pierre Yang and Kate Doust walked close by.

"Sorry guys, this is our workplace," Mr Scaife said.

"This is outrageous."

Asked if he would make a statement, Dr Krishnan said "not at the moment, when all is settled I will make a statement", which he said would happen in "a couple of weeks".

Dr Krishnan then appeared to be pulled into the building by Mr Yang before Mr Healy again stood in front of the cameras.

Mr Scaife then yelled to the media "you should be ashamed of yourselves" from inside the building.

'Extraordinary': opposition

Opposition Leader Basil Zempilas said Mr Scaife's comments were out of line.

"It would seem to me that the member for Cockburn has suggested the men and women of the press doing their job are a disgrace for doing their job," he said.

"The member for Cockburn should have a long, hard think about how things operate in here and around this space."

Mr Zempilas described the incident as "one of the most extraordinary things I have ever seen" and said the premier and Dr Krishnan needed to address the issue publicly.

"This government, for far too long, have done as they have pleased. Now, when questions are being asked, they don't like it," he said.
