British writer David Irving returned to England the day after he was released early from an Austrian prison -- vowing to repeat views denying the Holocaust that led to his conviction.

Irving said Thursday he felt "no need any longer to show remorse" for his views on the Holocaust, for which he was sentenced to three years in prison. Vienna's highest court granted Irving's appeal and converted two-thirds of his sentence into probation on Wednesday.

Upon arriving at London's Heathrow airport, he also called for a boycott of all Austrian and German historians until laws which make Holocaust denial illegal in those countries are overturned.
