A Number 10 adviser facing growing calls to be sacked over his past remarks also appeared to suggest MPs should pay attention to the "debate" around "very real racial differences in intelligence" when considering immigration controls, Sky News can reveal.

Andrew Sabisky has been employed as a Number 10 aide following a call by Dominic Cummings - Prime Minister Boris Johnson's chief adviser - for "misfits and weirdos" to apply for jobs in Downing Street.

Pressure is mounting on the government, which has so far stayed silent on the matter, after two Tory MPs called for his removal.

Labour is also demanding he be sacked due to past remarks about a "permanent underclass" being created by "unplanned pregnancies".

Mr Sabisky's purported previous comments on subjects such as eugenics, mind-enhancing drugs for children, FGM and women's sport have also recently emerged.

Further scrutiny will be put on the 27-year-old's views after Sky News uncovered a comment underneath a blog post in January 2014.

The comment is made by a user named "Andrew Sabisky" and using the same avatar as a Twitter account said to belong to Mr Sabisky.

It read: "As for race and IQ, I can only excuse the journalists here on the grounds of laziness, since the facts are perfectly clear to anyone who has researched the issue for more than 5 minutes (which I do appreciate is an awfully long time).

"There are excellent reasons to think the very real racial differences in intelligence are significantly - even mostly - genetic in origin, though the degree is of course a very serious subject of scholarly debate.

"That debate busily bustles on, and I'm sure we'll have more precise answers in another 5 years or so, though whether the politicians will pay any attention is debatable.

"It would be nice if they did from the standpoint of immigration control (in the UK, that is)."

Cannot believe No 10 has refused to comment on Andrew Sabisky. I don’t know him from a bar of soap, but don’t think we’d get on ....... must be no place in Government for the views he’s expressed — Caroline Nokes (@carolinenokes) February 17, 2020

Downing Street did not comment, with a spokesperson for Mr Johnson repeatedly refusing to say whether or not the prime minister agreed with Mr Sabisky's purported views.

Labour have called for the prime minister to sack Mr Sabisky, who has a Master's degree in educational psychology.

Ian Lavery, Labour Party chair, said: "It is disgusting that not only has Number 10 failed to condemn Andrew Sabisky's appalling comments, but also seems to have endorsed the idea that white people are more intelligent than black people.

"Boris Johnson should have the backbone to make a statement in his own words on why he has made this appointment, whether he stands by it, and his own views on the subject of eugenics."

Scottish First Minister Nicola Sturgeon posted on Twitter: "These are really not acceptable headlines for any government to be generating (or allowing to be generated).

"They need to get a grip fast and demonstrate some basic but fundamental values in the terms of our public debate."

Mr Sabisky's role was also criticised by Conservative MP Caroline Nokes, a former government minister.

She tweeted: "Cannot believe No 10 has refused to comment on Andrew Sabisky.

"I don't know him from a bar of soap, but don't think we'd get on ....... must be no place in Government for the views he's expressed."

William Wragg, who chairs the public administration and constitutional affairs committee, also tweeted: "Andrew Sabisky's presence in Number 10 is a poor reflection on the government and there is no way to defend it.

"He needs to go. 'Weirdos' and 'misfits' are all very well, but please can they not gratuitously cause offence. I cannot be the only one uncomfortable with recent Number 10 trends."

Environment Secretary George Eustice declined to comment on the growing row over the employment of Mr Sabisky, who has been described as a political forecaster, as a Downing Street adviser.

Speaking to Sky News' Kay Burley @ Breakfast show, Mr Eustice refused to say whether he would be comfortable with someone with such views about an "underclass" working in Downing Street.

"I have seen the reports that somebody's alleged to have had those views but I'm not going to get drawn on that," he said.

"I don't know the individual."

Mr Eustice added: "I'm not going to get drawn on the comments on that individual, that's a matter for Dominic Cummings and Number 10.

"I'm sure you can talk to them."

Sky News has attempted to contact Mr Sabisky for comment and confirmation he made the remarks.
