The last donation by the Weirs (July 2018) was £600K and was ring fenced to keep the Academy viable for a further 2 years.
Oh, and in addition to previously mentioned lower league clubs Inverness and Ayr, both Queens Park and Morton still manage to run Academies.
As for Falkirk, they didn't pull out of the Forth Valley Academy (effectively closing it) because they couldn't afford it, but as a gamble to free up further funds to invest in the first team to win promotion...a decision that with hindsight was obviously flawed!
Not forgetting that Dundee are now a lower league club lol !
