David Cameron conceded that there was nothing he could do to halt the European Court ruling that demands that British prisoners be given the right to vote. (More here from The Telegraph) Obviously prisoners forfeit some rights - for example their freedom - when they are convicted of a crime, but the courts ruled that the right to vote should remain.
It is interesting to note that our elected leader is powerless to effect the decision made by the higher democratic power in Europe, even though the MEP collective is only partly elected by British citizens and remote from them. And it is interesting to consider how prisoners may want to vote en bloc to achieve benefits for themselves. This may be even more problematic in Interactive Democracy if the general public, busy and preoccupied as they may be, don't consider votes instigated by "prisoner unions", who have all the time in the world to become involved. This may be good or bad, but, regardless, with ID the majority can change the system and over ride European diktats. That's democracy!
