Best man dies after speech.
Primary school teacher Julie Soper and airman Michael Morgan got married in front of more than 100 guests and with a full RAF guard of honour at St Thomas's Church in Brompton, North Yorkshire, on Sunday.
Rev Michael Snowball said: "It was a wonderfully happy day and then this terrible tragedy happened. We are all so shocked."
Ian, 25, who is believed to be a royal military policeman who served in the RAF alongside Michael, collapsed during the reception 8.20pm. His death is still a mystery.
Rev Snowball added: "I feel so terribly sad for this couple. One minute they're laughing, the next crying."
