Andy Murray and Kim Sears to tie the knot

Andy Murray is to marry his fiancee Kim Sears at the luxury hotel he owns in Scotland.

The couple are understood to be arranging the private service for April 11 at the five-star Cromlix House Hotel, close to his hometown of Dunblane.

The Wimbledon champion bought the venue in 2013, which has its own chapel, for STG1.8 million ($A3.55 million) and it opened last year after a refurbishment.

The hotel was the venue for his brother Jamie's wedding in 2010.

Murray and Miss Sears became engaged in November after being together for nine years.

Murray, who won the Wimbledon title in 2013, joked during an on-court interview at the recent Australian Open that he might wear a kilt with no underwear at their wedding.

He progressed to last Sunday's final in Melbourne where he was defeated by world No.1 Novak Djokovic.

The hotel where they will tie the knot was named Scottish hotel of the year in 2014 - just weeks after it opened its doors to guests.
