SNP leader Nicola Sturgeon and Tory leadership hopeful Sajid Javid have become embroiled in a Twitter spat on the issue of Scottish independence.
The social media spat began when home secretary Sajid Javid said were he to become Prime Minister, he would not allow a second Scottish independence referendum.
“People stated views clearly in 2014, so there should be no second vote,” he wrote.
“Nicola Sturgeon should spend more time improving public services in Scotland, and less time grandstanding.”
Less than an hour later, Ms Sturgeon hit back, and said Mr Javid had “a lot to learn about good public service delivery".
“A majority of Scots - independence supporters and opponents alike - will not accept being told by a Tory PM that we are not ‘allowed’ to choose our own future,” she wrote.
"And PS, you have a lot to learn about good public service delivery from the SNP gov."
Fellow Tory leadership hopeful Rory Stewart also weighed into the Twitter discussion.
“In everything we do and everything we say in this leadership race we should remember that the key is to unify the country and not divide the United Kingdom," he wrote.
When asked by another Twitter user whether he would consider allowing a second Scottish independence referendum, he said: “It is a no.”
Earlier this week Scottish Tory leader Ruth Davidson said she expects all 11 candidates for the Conservative party leadership to rule out a second independence referendum.
Ms Sturgeon had earlier said it would be a "democratic outrage" if Westminster blocked Scotland from holding a second referendum.
She added: “An independence referendum within this parliamentary term will give Scotland the opportunity to choose to be an independent European nation - rather than have a Brexit future imposed upon us.”
