I am in the process of applying for another job and the role is very similar to what I do now. The appl form asks me to give a reason why i wish to leave current job....now i can't say the real ereason (which is that the manager is an ignoramous) but also can't really give a good feasible reason 9such as wishing to upgrade carreers etc) as the job is pretty much the same as what i am doing now. Any ideas as to what to add that looks good and believable?
