The Mayor of London, Boris Johnson, has recommended that non-Muslims take the opportunity of the month of Ramadan to fast, along with their Muslim neighbors, in order to promote "understanding between cultures."

....There was no word on whether London Mayor Johnson was planning to suggest that Muslims and Christians fast on Yom Kippur in order to better understand their Jewish neighbors.
