Convicted,yes. Actually guilty, no. Jaime, Tyrion, Lancel, Olenna, Drogo, Mirri Maz Duur, Roose, Euron, Sansa, Brienne, Melisandre, Walder Frey... have I missed any actual kingslayers or those convicted by public opinion? Next in line to die are Mance, Euron, Tommen, Stannis, and Dany. The most likely kingslayers (or queenslayers) in my opinion are Mormont, Selmy, Jaime, Davos, and Asha. The next possible characters to commit regicide are Jaqen, Arya, Loras, Darkstar, Lancel, and the Blackfish. But this is all off topic anyway.

Egg, the topic is... Why do you always have to be right? You're annoying habit of making sense is starting to bother me. The English word conspiracy comes to us from Latin via French. Con means with.... spiracy comes from Latin meaning to breathe, i.e. Spirit was the unseen breath of God and Inspiration was the in breathing of God into the writers of the Bible. So we need to breathe together, if we are not breathing together, then we don't have a conspiracy.

Breathe in.

You think Tywin respected Cersei and Jaime? He had to know Cersei was a conniving, manipulative, ambitious uh, err, woman. Jaime was rash beyond rash and was particularly easy to manipulate... except for Tywin. Either Tywin had a huge blind spot for the twins or I think he kept tabs on them. I personally think he kept tabs on Cersei.

Breath out.

I think the spy who ratted out Jaime and Cersei would have feared for his life. Lord Tywin might have killed him for just brining the news and most certainly would have killed the spy just to cover it up... If this news had come out while Robert was living, then Tywin would have had to have killed Cersei, Jaime, Joffrey, Tommen, and Myrcella with his own hands if he had any hope of not joining the Reynes and Tarbecks.

Breathe in.

If Tywin failed to kill the spy, then both Cersei and Jaime would have sought out the informer on their own for pure vengeance.

Breathe out.

It seems to me that Pycelle (bought and owned by the Lannisters) knew about Cersei and Jaime. Yet he never said a word. I think he knew he'd never get rewarded for that information.

Breathe in.

I also think Varys and Littlefinger knew, but they kept that information to themselves for their own ends. Perhaps one or both still has concrete evidence of some sort that could topple Tommen from the throne... that is if Cersei does not accomplish this herself.

Breathe out.
