Let us pray that the sun shines tonight, at least in Islington, where the local Chabad branch is organising an al-fresco Friday night dinner in one of its fashionable squares. Enterprising Rabbi Mendy Korer has even secured a council grant towards its "Shabbat Under the Stars". One past Friday night diner, local MP Jeremy Corbyn, is not expected for cocktails and challah this time. "I imagine his schedule is quite busy," Rabbi Korer said.
