The National:

WE know the UK Tories openly display their contempt for Scotland, but you'd think they would treat potential donors with a bit more respect ... it seems not.

Twitter user @LauraAMcCormack shared a photo of a letter delivered to her elderly neighbours, which was intended to thank them for supporting a Conservative Government and included a donation form.

The letter was signed by Prime Minister Theresa May, and also talked about the importance of "making a success of Brexit".

Perhaps the first priority for Tory HQ should be making a success of mailmerge, as the message was addressed to "Mr Youmustbe Fuckingjoking".

And it opened: "Dear Mr Fuckingjoking, thanks to your support, our Conservative Government is building a Britain that is fit for the future."

How none of the Tory team spotted the error, had it filtered, or even got it wrong in the first place is still unclear.

The Tories have yet to apologise to the couple in question, but a spokesman said: “It is unacceptable that this letter was sent out and we apologize for any offence caused.

"We are currently investigating this matter to ensure it does not happen again.”
