I suspect that there will be a long hard look at every single recipient of CEA with regards to their ongoing eligibility. With a former 2* receiving custodial sentence plus a repayment order it sets the bench mark for any future cases of guilt.
I also don’t hold water with the “he just signed it without fully understanding it”. As a 2* he will approved many other subordinates CEA paperwork as he climbed the greasy pole - I suspect their paperwork will be the first under the microscope.
Makes you wonder what else he “signed off” without fully understanding the ramifications.
