What if Gladstone won the 1874 general election? Let's say his 1870 Education Act was more radical, and he also handled the Trade Union Acts better than IOTL (in which he put forward two contradict acts).
I think the domestic situation in Britain wouldn't be very different. But how would European political landscape differ from IOTL, especially the progress and the outcome of Russo-Turkish War, as well as other events like First Boer War and Afghanistan War? As we know, IOTL, Gladstone never wanted to support the Ottoman Empire, even opposed and openly condemned it in opposition?
