A Conservative MSP has been thrown out of the Holyrood chamber after he called Nicola Sturgeon a liar.

Oliver Mundell was ejected after raising a point of order about the First Minister and the Holyrood Salmond inquiry.

A special Holyrood committee is investigating how the SNP Government handled complaints of sexual misconduct against Salmond when he was First Minister.

Salmond pursued a judicial review and it was accepted the Government’s internal probe had been unlawful and tainted by apparent bias. The debacle cost the taxpayer more than £500,000.

MSPs are examining various aspects of the botched probe, including the development of the government’s anti-harassment policy, the judicial review, and how the actual complaints were handled.

However, the inquiry is in crisis amid claims of Government secrecy over information not being handed over.

The Holyrood committee convener Linda Fabiani has claimed the inquiry is being "hampered" by information being withheld.

Mundell told MSPs that Sturgeon had previously informed the chamber that the Government would provide whatever material the committee requested:

“Will the Presiding Officer ask the First Minister why she lied to parliament?”

Presiding Officer Ken Macintosh pulled up Mundell for using this word and demanded an apology.

Mundell said: “I apologise personally to you, Presiding Officer, but in this case I do feel it’s the appropriate word and I can’t find anything else that would express the sentiment.”

He added: “I think it’s disrespectful to the parliament for the First Minister to make a promise and not to keep it. I can’t withdraw the word, no.”

Mundell was then asked to leave the chamber.
