Chris Siddall and Denise Pickersgill will marry at Morley Town Hall on Saturday, when people across the nation are due to gather around their televisions to watch American ex-actress Meghan Markle walk down the aisle to Prince Harry at Windsor Castle.
Mr Siddall, 52, first met his fiancée, 55, at Morley’s Asda, where they work in the meat and checkout departments.
Mr Siddall said: “Nobody will forget our wedding day. Every time it comes around there will be something on because of Harry and Meghan’s big day, so it’s a good thing really.”
The day was already special for the couple, because their first date was on May 19, 2013 – and they often celebrate on the nineteenth day of each month.
The adult flight sergeant in the Royal Air Force Air Cadets will marry in service uniform.
After their 11am ceremony, the Leeds couple – who have three kids each – will head to Collingham Memorial Hall in Wetherby for a fancy dress reception.
The Royal wedding service begins at noon on Saturday.
