Kevin Pietersen says he is "so sad" that his international career is over.
The England and Wales Cricket Board unanimously decided to end Pietersen's international career on Tuesday after long, successful but controversial career.
His central contract, Sky sources understand, will be terminated shortly, with the two parties having agreed a financial settlement.
Pietersen finishes his international career as England's all-time leading run scorer across all formats.
But the talk on Wednesday morning in the national press was of some sort of confrontation between Pietersen and England captain Alastair Cook in the pavilion at Sydney.
Those allegations were denied by Pietersen's wife Jessica Taylor, who insisted on Twitter there was no confrontation.
And on Wednesday morning Pietersen wrote on Instagram, after posting a picture of his final Test in Sydney: "So sad that this will now be the last time I leave a field in an England shirt... Incredibly overwhelmed by the support overnight! Thank you so much..."
"I love England and I honestly hope they have every success in the future."
Pietersen played 104 Tests, 136 one-day internationals and 37 T20 internationals for England.
Speaking on Tuesday in a statement, Pietersen said: "Playing cricket for my country has been an honour. Every time I pulled on the England shirt was a moment of huge pride for me and that is something that will live with me forever.
"Although I am obviously very sad the incredible journey has come to an end, I'm also hugely proud of what we, as a team, have achieved over the past nine years.
"I feel extremely fortunate to have played at a time of great success for England cricket alongside some of the best cricketers the country has ever produced.
"I want to thank everyone for their fantastic support and I wish the team the very best of success going forward.
"I believe I have a great deal still to give as a cricketer. I will continue to play but deeply regret that it won't be for England."
