Check your LN ID, Spazzy. Northern Bretonia has been added to their ZoI to assist in the defence against Gallia.
RP reasons were covered by Fallen, although it seems his usual exaggeration and heavy bias
Going by my opinion here, the 'free' LN and GRN fleets are roughly equal, but the GRN have significant forces in reserve that need to be repaired in Leeds.
Leeds isn't some massive stronghold of BAF, anything above ground would be Valored to pieces pretty soon. The vast complex of mine shafts, quarries and bunkers underground house a significant resistance force to slow the repurposing of Leeds to the GRN's needs (and they do need it).
The GRN are currently trying to cut off Bretonia from Liberty given their main invasion routes have been severed. Manchester and Magellan are the most significant targets, although the former has some difficulty given the asteroid fields (their main invasion corridor to Edinburgh through Lewis was clear, Tau-23 had no significant forces to stop them, then they had gates for T-31 and Leeds).
BAF fleets are the majority of strength in Dublin and Cambridge, while they also have a presence in Manchester, New London and Newcastle where Liberty likely has more ships (along with the other various allies).
Lastly for ship quality, Liberty does have the most advanced because of DK research or something, while Gallia would come afterwards since it's been a big focus of their entire existence. Bretonian ships tend to be pretty old but sturdy, and most of those not in Cambridge have suffered lots of damage over the years.
