Thousands of couples at venues across the UK will reaffirm their wedding vows simultaneously on Saturday 8 February 2014 at 5:15pm. The Big Promise is attempting to achieve the world record as part of Marriage Week 2014.

The couples taking part in The Big Promise, launched in the Houses of Parliament during Marriage Week last year, hope to break the current world record of 1089 couples renewing their vows at the same time, which was set in America in 2009.

Tom and Doreen Shaw, from Sheffield, are celebrating fifty years of marriage on the day of The Big Promise. They can't wait to join with their friends, community and family to reaffirm their vows on their golden wedding anniversary.

Looking forward to the day, Doreen Shaw said: "We started out with nothing but our marriage wasn't built on what we had, rather on who we were. Marriage has made us better people I hope. We are so excited."

Dave Percival, Big Promise project coordinator, said: "The thought of thousands of couples from Newquay to Orkney saying together: 'We will' is just fantastic. The occasion will be both serious and huge fun – a bit like marriage really."

"Marriage Week (7-14 February), incorporating Valentine's Day, exists to encourage and celebrate couples and all that marriage means for them and for society. The promises we make are important. They offer the foundation for a stable and loving family; what we build on that foundation is up to us. We want people all over the country to join with us and send out the message that these promises matter."

Couples can still sign up to be a part of the world record attempt by finding a participating venue on The Big Promise website or by registering a new venue themselves.
