Scottish Conservative deputy leader Rachael Hamilton said Constance – whose attendance at the game was first reported by the Daily Record – had “learned nothing” from the Gray “scandal”.

“The public will be astonished that Angela Constance deemed it appropriate to use a ministerial car to go to the Old Firm this weekend,” she said.

“It’s no wonder public trust in politicians is at an all-time low when senior SNP figures are using taxpayer-funded limos to take family members to football matches, all under the flimsy pretence of ministerial duties.”

The government revealed this week, external that ministers were joined by either partners, friends or family members at official events 49 times in the past three years.

For four of those events, ministers were accompanied by their guests in ministerial cars. The government said it did not hold the travel information for all the other engagements.
