Mr Cawley, who describes himself as a ‘politics nerd’ and teacher on Twitter, directed the posts at politicians including Labour leader Jeremy Corbyn and the SNP’s Keith Brown and John Mason.

In one post related to Brexit and directed at Scottish Labour leader Richard Leonard, he wrote: “The state of this delusional p*** Mitigate a f****** disaster your pal is complicit in, Mason, Bastani, Milne, Corbyn and McDonnell et all can f*** off.”

One parent said: “To swear so extensively is unacceptable for someone who teaches young people and who is expected to set an example to them.”

A council spokeswoman said: “A complaint has been received about inappropriate tweets that are against the council’s employee code of conduct and an investigation is currently taking place.”

The non-denominational school is part of the Whitehill Campus, along with Golfhill Primary School and Westercraigs Nursery in the city.
