Thanks to Eric and Rasmus who replied.

I did try using a double-underline but it looked so horrible I changed
it very quickly!

This is what I've ended up using -

I've saved it as 'code-1.tex' and just use it as '#+latex_header:
\input{/home/boudiccas/research/code-1}' at the end of my package list
in my org-mode source document.

And its now working perfectly. 

Thanks
Sharon.
