It is not possible, repeat not possible, under UK FTL's to operate to the the Gulf and back in one duty period.
Please be aware that there are some contributors to PPRuNe who will intentionally post inflammatory rubbish in pursuit of their own personal agenda: There is an established history of such activities on QF related threads and a cursory look at previous posts from captainrats will very quickly show you where things are coming from in this particular instance.
This doesn't mean that there won't be changes in the future for UK based QF crew - I have absolutely no idea what the future hold for any of us, including myself. What is absolutely certain however is that under present UK FTL's, nobody will be operating round trip Gulf flights, a duty period that would be closer to 17 hours on a two sector duty.
