The leaders of all the main Dutch political parties have issued a joint appeal for an end to threats and intimidation in the debate over refugees.
The appeal, organised by GroenLinks leader Jesse Klaver, is published in Wednesday's Volkskrant and calls on people to 'stop intimidation and threats'.
'Meetings are being shouted down by people with whom it is impossible to have a reasonable discussion. Concerned citizens are being accused of racism. People are swearing at each other and wishing each other unspeakable things on demonstrations,' the letter states.
