Re the regulations on the banking industry in UK too loose to make them vulnerable in the financial crisis back in 2008?

Im expecting a 2-1 work here.
The examples use in the dissertation is better on UK basis, please quote one or two UKs banks which have gone bankrupt in the financial crisis as examples, and and talk about is there a loophole in the regulations back in that time which people criticize where managers can use them to maximize their own benefit
also, can I have the conclusion on the effects of the financial crisis and what have it changed the regulations, whats added in the regulations or is there any adjustment on the regulation because of the chaos brought by the financial crisis
Sorry for the poor English, if there is anything you dont understand, please, feel free to let me know, I will try my best to make that clear
