I had a think about this.

Example: our PM, a man of Indian heritage (though British) who speaks RP.

An Indian man with a really strong accent is going to be judged as being significantly lower status.

I think it'd be the same pretty much across the scale. Like imagining a Polish software developer vs a builder and the latter would probably have a rougher accent.

A strong southern American accent, etc.
