Thousands of Sikhs will gather across Europe Sunday to proclaim their right to wear their faith’s required turbans — and to voice concerns with legal challenges to such headgear in some parts of Europe.

The turban or dastaar is mandatory for devout Sikh men. They are not allowed to remove it even to wear safety headgear such as motorcycle helmets.

Thousands of turban-wearing Sikhs are expected to gather in European capitals in a simultaneous gathering organized by the Sikh Channel, a Europe-wide TV Station on the SKY platform.

Live broadcast on the Sikh Channel the Turban Awareness Gatherings will take place from Madrid, London, Rome and Brussels.

Sikhs in Italy have complained of difficulties at some Italian airports of being asked to remove their turbans, with many Sikhs refusing to do so and, as a result, missing their flights. Some Italian provinces require Sikhs to remove Turbans for driving licence photographs. Thus, a number of Sikhs have not applied for driving licenses to avoid what they consider the humiliation of being photographed without their turbans.

The British gathering is expected to occur at noon outside of the Houses of Parliament. In Rome, Sikhs will gather at the Piazza Montecitorion.
