In page Eurovision Song Contest 1968:

The documentary claimed that the contest should in fact have been won by the United Kingdom's entry – "Congratulations" performed by Cliff Richard – which finished second by one vote.[4] Massiel, the performer of the winning entry, was outraged by the allegations, and claimed that if there had been fixes, "other singers, who were more keen on Francoist Spain, would have benefited". José María Iñigo, author of the statement in the documentary, personally apologized to Massiel and said that he had repeated a widespread rumour. Both Massiel and Iñigo accused television channel La Sexta, broadcaster of the documentary, of manufacturing the scandal.[5]
