No, not the UK cricket ground.

Does anyone know what the title 'Lord' indicates at Imperial level? (I appreciate that on individual planets the title might be applied all over the shop - including religious figures). I have some vague recollection of it indicating a Count but can't find the reference. Does it 'mean' something definite, or can it be a variety of things, or is there no formal / definite meaning?

Sorry, brain a bit slow at present.

Cheers
