Several stakeholders raised this as needing to be fixed at a recent 'surgery'.

UM requires LAM's which are not on a rotated pole to be described with bplat=90 bplon=180. Iris will currently set bplon to 0. The recent introduction of UM file metadata checking means that such incorrectly set bplon values will raise an error in the UM.
Our workaround is to override pp fields derived by iris:
https://code.metoffice.gov.uk/trac/ancil/browser/ants/branches/dev/carwynpelley/1169_IRIS_DITCHES_BPLAT_BPLON/lib/ants/fileformats/pp/__init__.py?rev=8607#L207
It would be simple enough to apply a similar change to iris pp generation from cubes by overriding bplon as 180 if the provided field is a LAM with unrotated pole crs.
