More on Livingstone's Venezuelan adventure as Andrew Pelling raises the awkward human rights question:
Andrew Pelling: What understanding do you have with the Venezuelan government that transfer of technologies for genetic fingerprinting will not be used for abuse of human rights in Venezuela?
Ken Livingstone: There is no evidence that fingerprinting technology has been used to abuse human rights in Venezuela. I have no reason to believe that the government would use the technology to do so in future.
Fingerprint scanning machines have been used in Venezuelan elections since 2004. These elections have been observed by international bodies including the Carter Centre and the OAS (Organisation of American States) and deemed free and fair.
I am sure you will join me in condemning the real threat to democracy and human rights in Venezuela which comes from those who supported the unsuccessful military coup against President Chavez in April 2002.
If the technology is so good, perhaps it should be brought in for some East London boroughs at election time - and we can draw our own conclusions from the final paragraph....
