I don’t doubt the validity of the quoted graph but interested in the source.

Have had a dig around. FullFact concluded that this exact graph is overstated - tax evasion is not 360x higher than benefit fraud - but TE still vastly outpaces BF, and could be as much as 14-19x larger. An annoying exaggeration considering the wider point still stands! fullfact.org/online/tax-g...

It’s not true that ‘lost’ tax revenue is 360 times greater than benefit fraud - Full Fact

An annotation suggesting that a graph shows tax evasion, avoidance and non-collection costs the government 360 times more than benefit fraud is incorrect.
