Moon was sighted in Chile and Guyana on Saturday night , and the sightings were accepted by various organizations, although this doesn't affect the UK situation.
What makes you think that Scholars are well versed in Moon Sighting? In my experience, majority of the Imams are clueless of the Fiqh let alone actual Moonsighting.
Shaykh Suliman Gani goes around the world and does actual MoonSighting and is extremely well versed on the subject, how many Ulama do you know who do this month after month?
Try stopping a random Imam (of a Mosque) and ask “which direction do you turn to when looking for the Moon?”
This cannot be undone and I am sure it will be greatly appreciated.
