Ian Blackford has opened a debate on the conduct of Boris Johnson.

The SNP's Westminster leader launched the opposition day debate in the Commons as the Prime Minister was delivering an update on Coronavirus. 

Prior to the session, the Commons Deputy Speaker Dame Eleanor Laing warned MPs about their conduct, saying "intemperate abuse" was "out of order".

However, she added, that "things may be said which the chair would not normally permit."

The SNP scheduled the debate to raise their concerns about the ongoing claims of corruption and sleaze within the Conservative party, and within Government in general. 

They have specifically called for Mr Johnson to be censured for his alleged role in the scandals, and for his ministerial salary to be reduced by half. 

Mr Blackford was heckled repeatedly from the opposite benches as he gave his half-hour speech.

He said: "This Prime Minister is at the centre of the sleaze and corruption - he is orchestrating much of it

"I’m afraid corruption is the only proper word - the only honest word - for what has been going on."

He read a list of occassions when he claims Mr Johnson had not been honest, explaining that "the truth and the Prime Minister have always been strangers."

Mr Blackford added: "On the 4th of March 2020, the Prime Minister said ‘We have restored the nurses’ bursary’ - completely and factually untrue.

"On the 17th of June 2020, the prime minister said there were 400,000 ‘fewer families living in poverty now than there were in 2010’ – both ONS and the Children’s Commissioner have confirmed that is false.

"On 7th November 2019, the Prime Minister told Northern Ireland businesses – in person - that the protocol would mean ‘No forms, no checks, no barriers of any kind’ – once again, clearly not true."

In a claim which shocked MPs, Mr Blackford continued: "I can only conclude that the Prime Minister has repeatedly broken the six principle of public life.

"I can only conclude that the Prime Minister has demonstrated himself to be a liar."

Tory MP Mark Jenkinson raised allegations as he asked the SNP’s Westminster leader to “update us on the missing donations, and the fraud investigation into the First Minister’s husband, your party’s chief executive”

The MP for Ross, Skye and Lochaber replied: “All monies that are raised by the Scottish National Party for the purposes of fighting an independence campaign – I will give you a guarantee, I will give you a promise, I will give you a commitment right here and now, that every penny which is raised will be spent on independence campaigning because that’s what we’re about.

“And there is a big difference to those that fund the SNP and fund the independence campaign, because I will give you another promise – not one single member of the SNP that gives to us willingly will end up in the House of Commons.

“What they will be doing is they will be funding the SNP and independence movement to make sure that we deliver on our promise of taking Scotland out of this union.”

Also in the debate, Labour MP Dawn Butler said: “If we have a Prime Minister that comes to this House and fails to tell the truth, that is fundamental to how our democracy works in this country.”

Paymaster General Michael Ellis MP said the SNP’s calls to censure the Prime Minister for his conduct are like pantomime season come early.

Mr Ellis said: “I must confess some surprise when he, with this rare opportunity to engage in serious debate with the Government – and I haven’t been to a pantomime in quite some time – but instead he opts to launch pantomime season in the month of November, complete with an over-the-top characterisation of the Prime Minister, who clearly he wishes would disappear in a puff of smoke.

“But the reality is, when it comes to fanciful fairy tales, the Scottish National Party are expert, and I venture that neither this House nor the people of this country will appreciate the over-the-top performance nor recognise, I have to say, the absurd depiction of the Prime Minister, a hugely popular Prime Minister of this country, who returned this House with an 80-seat majority and is getting on with the job of building back better.”

Mr Ellis then listed the Government’s agenda since coming to office, including on infrastructure, and building new hospital facilities and schools.

He emphasised that the UK Government was “committed to levelling up across Scotland”, and that Scotland was receiving £41 billion a year in Barnett Formula-based funding.
