For the 27-year-old’s many fans and friends in the town, it means at least part of the wedding of the year will be a spectator sport, played out on the streets of the community. It is understood local residents and businesses urged the former Wimbledon champion to hold the April 11 service at the cathedral rather than at Cromlix House in nearby Kinbuck – so they too could toast his big day. The 300-seat, 12th century cathedral is much bigger than the chapel at Cromlix, which seats only 28. Thousands are expected to line Dunblane High Street on the day. Murray’s uncle Niall Erskine said: ‘I’m sure it will be a popular decision, as he’s had so much support from the people of Dunblane in the past. ‘Andy is looking forward to bringing all his family and friends to Dunblane. I’m sure lots of people will come down to see the cars as they go past and it will be a very popular day.’ Kim, who showcased her engagement ring on Tuesday, and Andy will tie the knot at Dunblane Cathedral on April 11 .
