Heavy rain stayed away for most of the morning as guests streamed into the 12th-century church. A downpour erupted minutes after the ceremony started and ended just seconds before the 45-minute ceremony concluded.

The ceremony took place just a few miles from the Middleton estate, where the marquee reception was held. Classic cars also brought page boys and bridesmaids from Middletons' home minutes before the bride's arrival, the PA reported.
