There was a special case established under the State Management Scheme where the brewery and licensed premises were bought and run by the state until 1973, most notably in Carlisle. During the 20th century elsewhere, both the licensing laws and enforcement were progressively relaxed, and there were differences between parishes; in the 1960s, at closing time in Kensington at 10:30 pm, drinkers would rush over the parish boundary to be in good time for "Last Orders" in Knightsbridge before 11 pm, a practice observed in many pubs adjoining licensing area boundaries. Some Scottish and Welsh parishes remained officially "dry" on Sundays (although often this merely required knocking at the back door of the pub). These restricted opening hours led to the tradition of lock-ins.
Output:
What was the mandated closing time of pubs in Kensington in the 1960s?
