Mr Livingstone said he had been invited by British Olympic Association chairman Lord Moynihan to attend the International Olympic Committee's Sport for All congress in Havana, Cuba. He spent about 30 minutes there at the closing press conference. Then, after the Venezuelan leg of his tour was cancelled, his four-and-a-half day stay in Cuba had to be extended by another day so he could catch a flight home.
Defending his trip, Mr Livingstone told a City Hall press conference this morning: "Of course I am not happy. I will have to go separately to Venezuela when I open the office there. I will miss my children. I will have to go to the airport, which I hate, have a long flight, which I loathe, and rush back as soon as possible."
Oh the burdens of Office.
