Caborn insists the decision to offer Sheffield as an alternative venue to London for the Championships was taken without him, by Culture Secretary Tessa Jowell, because as an MP from that city he was excluded from the process.
The Minister also denied that he offered scholarships for African athletes and sightseeing trips around London for IAAF delegates. He also rejected claims that he invited the partners of IAAF officials on shopping trips to Harrods.
Caborn said: "What we told the IAAF was that if they wanted to hold their Congress in London we would facilitate that, and that if they want to see the sights - Number 10, the House of Commons and so on - then we would help with that too."
He is particularly upset by allegations from IAAF officials that he talked in "colonial" language to the IAAF's Senegalese president Lamine Diack by suggesting Britain would give "bursaries to you Africans at our new training centre in Sheffield".
Caborn described the claims as "grotesque" and said: "As a campaigner for equality in South Africa for over 30 years I was insulted by that.
"In his conference speech last week, the Prime Minister challenged us all to forge closer links with African states, and that was why we made our offer of scholarships for young African athletes.
"It is a great shame the IAAF felt free to dismiss this so readily and in such a lofty manner."
