Ian Blackford, the SNP's leader at Westminster labelled RT a “vehicle of the Russian state” and said he didn’t believe anyone should broadcast on it.

It came after two Russian nationals were named as suspects were named in the attempted murder of the Skripals.

Mr Salmond, who resigned his SNP membership last week amid sexual misconduct allegations, has previously raised doubts about Russia's role in the nerve agent attack.

In March he used the show to argue there was not enough evidence to blame Vladimir Putin's regime.

Mr Salmond echoed Labour leader Jeremy Corbyn saying the case had to be "cast iron".

He also also spoke to former MI5 officer Annie Machon who claimed that Russia may not be behind the poisoning.

During the broadcast a ticker tape on the screen said the UK had not carried out a "thorough probe" into Salisbury attack before it expelled 23 diplomats.

The show is produced by Slainte Media Ltd, set up by Mr Salmond and fellow former SNP MP Tasmina Ahmed-Sheikh.
