Interesting development but if there was any overspending I don't think the organisations exist any longer for any fines etc to be levied.

EU referendum campaign spending probed
The spending returns of the Stronger In and Vote Leave campaigns in last year's EU referendum are under investigation, the Electoral Commission has announced.
A total of more than £32m was spent on the campaign - with the Leave side funded by donations totalling £16.4m, outgunning the Remain side's £15.1m.
