Second trial by combat of Tyrion Lannister

"I did not do it. I didn't kill Joffrey, but I wish that I had. Watching your vicious bastard die gave me more relief than a thousand lying whores. I wish I was the monster you think I am. I wish I had enough poison for the whole pack of you. I would gladly give my life to watch you all swallow it."

- Tyrion Lannister to Cersei Lannister and the royal court.

The Trial of Tyrion Lannister is an event during the late stages of the War of the Five Kings. Accused and arrested for the assassination of King Joffrey at his wedding feast, Tyrion Lannister is tried by his own father, Tywin Lannister, along with Prince Oberyn Martell and Lord Mace Tyrell.

In the books
In the A Song of Ice and Fire novels, Tyrion's trial is longer, taking the span of several days. A number of witness are brought by the crown, some of which even consider Tyrion to be innocent, but nevertheless do lend credence Cersei's case. Others, however, seeking the Queen's favor, state outright lies, going as far as claiming they saw Tyrion put something in Joffrey's cup.
