Kamara, the former Bradford City manager, took over at Stoke in January after signing an 18-month contract. It took 12 games before he guided the club to victory, and last Saturday's 2-0 defeat at Reading was the last straw. During Kamara's spell in charge, the club has slipped from 15th to last place in the division.
"I am disappointed that things have not worked out as I expected," Kamara said. "I have enjoyed working with the board and under different circumstances and with a little bit of luck things could have been so much better. "
The Stoke vice-chairman, Keith Humphreys, said Kamara left the club by "mutual consent" and a settlement had been reached over the remaining 13 months of his contract.
"Most people thought Chris's appointment would be a good one, but it hasn't worked out," Humphreys said. "It has been a nightmare time for all concerned and we wish Chris all the best in the future."

However, an FA spokesman said: "As far as we are concerned the matter is now closed."
