Thomas thank you for your answer,

I was thinking more of how to modify babel so that it would generate the
results block with the relevant exporter attribute parameters so that it
play nicely.
That is, the results block contains the directive it needs at the moment
the #+results block is bare and has no extra information for latex to pick
up and format correctly.

Kind regards.
