Colin Jackson says plans to erase sport's world records are "ridiculous"
Welshman Colin Jackson has said proposals to erase all world and European records set before 2005 are "ridiculous" and would "rob memories" from fans.
The proposals are part of controversial plans to fight doping in sport.
European Athletics said overhauling the record lists will eliminate any doping doubts surrounding outstanding performances.
The IAAF has only stored blood and urine samples since 2005 and said all records before then would fail to meet its new three-point criteria for new standards.
Women's world marathon record holder Paula Radcliffe and men's triple jump world record holder Jonathan Edwards have also both condemned the move that would see theirs and others' historic achievements wiped out.
Speaking to 5 Live, Jackson said achieving medals was the "primary objective".
Cardiff-born Jackson's indoor 60m hurdles world record of 7.30 seconds, set in 1994 is amongst those records at risk.
British Athletics believes it will no longer be recognised as official if the new proposals are brought into force.
Others include:
Steve Cram's European one mile run of 3 minutes and 46.32 seconds (1985) and European 2,000m run of 4 minutes and 51.39 seconds (1985)
Jonathan Edwards' triple jump world record of 18.29m (1995)
Paula Radcliffe's women's marathon world record of 2 hours 15 minutes and 25 seconds in a mixed race (2003).
IAAF president Lord Coe endorsed the move as a "step in the right direction" as the sport fights for "credibility" over doping testing.
