I personally think Liberal Reforms is the most likely to come up. This is because if you look at previous years almost always there has never been the same topic in June as in January, thus Home Front is least likely to come up. And because Liberals came up last June it would seem Suffragettes is most likely. However if this was the case you could just follow the pattern and predict that Suffragettes would come up tomorrow, instead they need to break the pattern at some point and because Home Front was in January I'd predict Liberals is the most likely! (This doesn't mean you shouldn't revise all three, they could just throw a screwball at you and come up with Homefront, ALTHOUGH VERY UNLIKELY!)
