AMSTERDAM (Reuters) - Dutch far-right politician and anti-Islam campaigner Geert Wilders said on Friday that Twitter had temporarily blocked his account following remarks he made about a political rival.

Wilders, who cannot easily appear in public due to threats against him by Islamists, relies heavily on Twitter to communicate with his supporters. He has 811,000 followers, second only to Prime Minister Mark Rutte among Dutch politicians.

“Twitter often tolerates death threats against me, but not a factual tweet by me about a colleague. Madness!,” he said in a statement.
