I have no idea how long you have been at Lye but if you have been there for years and have used the CEA system to put your kids through private education then to the my very simple mind you have knowingly and willfully committed fraud.
Having moved every 2-3 years I came back to Lyneham expecting one tour & off again. As it's transpired I have been here for some time. Yes, I used CEA to give my kids certainty in their education, with hindsight I probably didn't need to, but as I said, that's with hindsight. If I'd asked my desk officer how long I would stay at Lyneham, considering the 4 moves in 6 years I'd just done (including one of my children in his second school at the age of 5), he would have been reluctant to commit I'm sure.
Knowingly and willfully committed fraud? That would imply I knew I wasn't going to move, which I didn't. If I'd used the state system & then had to move my family because I was posted then I'm sure I would have, with hindsight, regretted not taking up CEA.
