Jeremy Corbyn is considering standing for election as an independent candidate for mayor of London.
The Islington North MP appeared at the Edinburgh Fringe Festival on Saturday alongside former Unite general secretary Len McCluskey.
Asked about the prospect at an All Talk event with broadcaster Iain Dale at the Edinburgh International Conference Centre, he said: “Well let's have a think about it, shall we?
"I want to see change in our society. I'm not disappearing, I'm not going away.
"I look at my diary and I'm more active than I have ever been at any other time in my life."
Earlier this year, Corbyn also told the LBC radio station he was "not ruling anything in and not ruling anything out" about his future in politics.
Asked if he was considering standing in his Islington North constituency as an independent, which he has represented since 1983, he went on to say: “I'm very happy and very proud to be the MP for Islington North.
"I live in the area, I know large numbers of people in the area.
"I have learned a great deal from the people I represent. I am available to represent the people if that is what they wish."
The 74-year-old was elected as leader of the Labour Party in 2015 and resigned following a historic defeat at the 2019 general election.
He was ousted from Labour earlier this year following a row over antisemitism.
