Scotland's former finance minister will receive a controversial pay-off of almost £12,000 after his resignation as a Scottish minister, it has emerged. 

Shamed Derek Mackay stood down from his former role after it was revealed he was sending unwanted 'predatory' text messages to a 16-year-old schoolboy.

Scottish legislation has stated that after 90 days he will automatically receive an "office holder resettlement grant" which is the amount of three months' salary. 

Including his £63,579 basic salary as representative MSP for Renfrewshire North and West, Mr Mackay earned an extra £47,780 a year as a Cabinet secretary. 

Now, the mother of the schoolboy who fell victim to the unwanted messages is calling on the £12,000 pay off to be given to charity.

She told The Scottish Sun: "I know it's normal for politicians to get money when they leave as it's part of the contract - but this is a different situation."

"I don't think it's right that he should be given this money." 

"He already has a good life and a good career." 

"Most ordinary people will never get a £12,000 payment in their life so why should he get this reward after what he's done?" 

"It should be donated to a chariy. They would deserve it - he doesn't."

A Scottish Parliament spokesperson said the parliament’s Corporate Body had no power over making the payment: “The legislation says the SPCB must pay the grant after 90 days. It is a matter for the member thereafter.”
