The 32-year-old Glasgow Warriors star confirmed the news in an Instagram post on Monday.

Jackson featured 33 times for his country and declared he had lived his "childhood dream".

He is now set to pursue a new career in the drinks industry.

"It is not the fairytale ending I may have dreamed about, but I want to say a huge thank you," he wrote on Instagram.

"I have achieved more than I could ever have dreamed of, but it is now time to embrace a new challenge.

"I have been so fortunate to live out my childhood dream of playing rugby, not just professionally but for my country.

"It has been a journey that has allowed me to travel the world, make some incredible friends and, without doubt, has given me some of the happiest days of my life.

"I have played at some amazing clubs: Wasps, Harlequins and, of course, two stints at Glasgow Warriors, which will always hold a special place in my heart. The supporters will be one of the things I will miss most."

Jackson debuted for Scotland in 2010 against New Zealand and went on to score 37 points on the international stage.

Having started out with Glasgow, he returned to the club in 2017 following spells with Wasps and Harlequins.
