Other countries manage it and so could we. Replacement legislation does not have to be more complex.
Maybe so, but just as keeping people in prison costs the taxpayer money, so does the entire panoply of deportation procedures and the latter also risks invinting reprisals; I'm not, of course, suggesting that this of itslf means that there is no reason to deport anyone - just that there's no such thing as an other than expensive lunch where this kind of thing is concerned. No one can be deported from any country without laws supposedly governing deportation being in place and those laws cost a fortune to create, change and carry out. Another issue, of course, is the risk of wrongful conviction; we've had our fair share of that in UK when people have been imprisoned, sometimes for many years and then released as a consequence of their original conviction being overturned and there can be no reasonable expectation that the conviction of illegal aliens for terrorist or other criminal activities will necessarily be any safer than those of legitimate citizens.
Bear in mind also that very conceivable law and regulation ever devised by mankind has been and will continue to be bent by someone somewhere to his/her advantage and that this is just one reason why laws will forever become more complex and, as a consequence, more expensive and require ever more lawyers and legislators to maintain this ever-burgeoning industry; it has been said with good reason, for example, that the tax laws of many "civilised" countries are as complex as they are mainly beacuse of the loopholes that have been found in those laws when they were simple...
This government has deportation targets that they are not hitting. Ministers know what is hindering the process and eventually this Act will go.

Perhaps they are either short-staffed or there is an insufficiency of will to meet those targets, either through lack of interest, the risk of PR gaffes or fear or internal and/or external reprisals...
