There are limits to plea bargains in the UK. One such limit is that a bargain can only be made if prosecutor and defendant agree upon the defendant pleading guilty on some charges while the remaining charges are dropped. Moreover, the court still has to decide on the appropriate penalty (considering only the charges that haven't been dropped, of course), that is there is no binding agreement on penalty between prosecution and defendant. Plea bargaining does happen in the UK and can be problematic in those cases but it's nowhere near as excessive as in the US.
