Begum loses appeal against removal of British citizenship.

We know it's eventually going to happen anyway. Her legal team, fat on the revenue that they are getting from the British taxpayer, are keen to pad out the process for as long as possible so there will be appeal after appeal after appeal until it eventually goes to the ECHR who will rule that it was unlawful to remove her British citizenship in the first place and demand that it be reinstated. There might be a couple of appeals after that, but eventually she will return, after which the next decade or two will see her legal team raking in even more money from the taxpayer as they determine how much money she should get in compensation for her distress. I could write the script for this already.

Perhaps they will eventually turn all of this into a Hollywood movie! If they change ISIS, which has a somewhat scummy reputation, to a more palatable freedom-loving terrorist group, like the IRA, the Yanks will positively lap it up.
