Bolton Town Hall will be lit up orange as part of an international day to raise awareness of a rare genetic disorder.

Landmark buildings across the world will also be illuminated orange in support of those affected by PWS and encouraging participants in the 'Move it May' fundraising campaign to visit their nearest orange-lit landmark.

Today is Go Orange Day, which is always held on the last Friday of May.

It is the one day when people across the globe wear something orange in support and to raise awareness of Prader-Willi Syndrome.

Prader-Willi syndrome (PWS) is a rare, complex genetic disorder that affects both males and females from birth and throughout their lives.

It causes low muscle tone with consequent motor developmental delays, a mild to moderate learning difficulty, incomplete sexual development, and emotional and social immaturity, which can lead to challenging behaviours.
