Horan, who was sacked from the priesthood by Pope John Paul II in January 2005, has declared his intention to protest outside the Olympic Stadium in Berlin next Sunday, carrying placards with the words: 'Adolf Hitler was a good leader, he was raised up by Christ to punish the Jews, says the Bible.'

Horan achieved worldwide infamy in 2003 after he ran on to the track at the British grand prix at Silverstone, dressed in a kilt, proclaiming that people should read the bible. He was imprisoned for three months in the UK for "aggravated trespass". Outside the court, Horan did one of his Irish jigs, which he describes as his peace dance.

The eccentric Kerry-born priest was at it again in 2004, when he disrupted the 22km walking race at the Athens Olympics, knocking the race leader, Vanderlei de Lima of Brazil, into the crowd and relegating him to third place.

The Greek authorities handed him a 12-month prison sentence but to the annoyance of Horan's family, who live in Kerry, it was suspended for three years.

Horan promised after Athens that he would no longer disrupt world sporting events "because the Bible only told me to do it twice".

But he is now targeting the World Cup final in a country which is very sensitive about its history. Another of his placards . . . which Horan promises will be in five languages, including Irish . . . proclaims;

"Auschwitz was good; it led to the birth of Israel, says the Bible."

Following his final appearance, he plans to go to the old Gestapo Headquarters in Berlin. "I will give the Hitler salute; do my peace dance and read a verse, in German, from the Bible, " he said.

A spokeswoman for the London Metropolitan Police said that Horan, who lives in south London, was issued with an anti-social behaviour order (ASBO) after he threatened to disrupt the London marathon last year. The ASBO has since expired, she told the Sunday Tribune this weekend.

"We cannot stop him travelling to Germany but as his planned protests are almost certain to attract trouble outside the stadium, we will be alerting the Berlin authorities that he is on his way, " she said.

A spokeswoman for the Department of Foreign Affairs said it was aware of Horan's threats but had no plans to intervene.
