I dont think they would waste them anywhere in UK......
What?! There homeland, the biggest aviation sector in Europe the UK?!
I think that if EZY were to expand in the UK it would probably be in the North as that is where airlines such as FR are weakest, only having one base and DUB and SNN connections from the other airports. LBA could be a possibility. LS have been daring enough to enter EZY territory in NCL, BFS and a little in EDI, and EZY are not shy of doing it either - STN (FR) and LGW (BA).
Anyway, next base would be expected in continental Europe surely
