Definitely Leicester, they may not be Russell Group but I would have picked Leicester if I had not got a place for the LLB at a Russell group. Probably the best non Russell group uni you can go to for the LLB, and as others have said, they do very well with the Magic circle and big city law firms, so if commercial law is your goal, I would pick ahead of Kent for sure. Birmingham would be good if you get it, a strong Russell Group, but I would not advise Liverpool, they let people in with BBB and lower and so their reputation in the Russell Group is not that good. Good Luck!!
