# How to keep LyX from using babel?

I'm writing a document using the copernicus_discussions.cls document class. This document class doesn't work when using babel. So I need to keep LyX from automatically using babel. However, even though in Tools->Preferences->Language I selected "Language package: None" and disabled all checkboxes on that page, and even though in my document preferences, I selected "Language package: None", the generated LaTeX source still contains the line

\usepackage{british,english]{babel}

How can I prevent LyX from inserting that line?

What's wrong with using babel with natbib? –  Joseph Wright Sep 27 '12 at 16:52
as I wrote in the question, the copernicus_discussions.cls class doesn't work in conjunction with both natbib and babel. More specifically, LaTeX gets sent into an infinite loop at the first \citet or \citep command. –  andreas-h Sep 27 '12 at 17:18
I just realized it also happens when using \cite, so it's not natbib dependant –  andreas-h Sep 28 '12 at 8:15
There used to be a Lyx mailinglist, some years ago I got a usefull answer there, my question then also aimed at Lyx internals. –  Keks Dose Sep 28 '12 at 9:34
