Kinnock wrote to Uefa bosses over Wales' 1976 Euro defeat
Ex-Labour leader Lord Kinnock was so upset about Wales' failure to qualify for the 1976 European Championship semi-finals he complained to Uefa.
He told BBC Radio 5 live he was in the crowd at Cardiff's Ninian Park for the quarter-final defeat by Yugoslavia.
The bad-tempered second leg featured two disallowed Welsh goals and a controversial penalty for the visitors.
Lord Kinnock said he complained to Uefa about the referee's performance and the fact he "wasn't even admonished".
Yugoslavia reached the semi-finals after winning the home leg 2-0 and drawing 1-1 in Cardiff.
In an interview broadcast on Friday, the then MP for Bedwellty said: "In '76 we nearly qualified, of course.
"We had to beat Yugoslavia - I was at Ninian Park, the East German referee [Rudi Glockner] was horrific.
"I felt so strongly about it that I wrote to Uefa, a very formal letter on House of Commons notepaper, saying that the refereeing and the way in which he wasn't even admonished brought the game into disrepute."
Lord Kinnock said he was still waiting for a reply.
He described Wales' Euro 2016 appearance - their first at the final stages of a major tournament in more than half a century - as "the pot of gold at the end of the rainbow".
