my partner got a letter from the DWP sayings he must attend an interview to help them withh their enquires into fraud investigation. We don’t claim any benefits my partner works full time so i am confused and not sure what it’s about and neither does he know and he called them and they won’t tell him on the phone. Also I’ve googled about it and it says if the letter says you must attend an interview under caution... but his letter does not say that. Does anyone know what this could be about?
