Christian leaders have today unveiled plans for a major evangelistic initiative in London.

London 2013 is to build on the outreach work carried out during the 2012 Olympics by the More Than Gold church coalition.

The new initiative's Chairman Stephen Gaukroger outlined the vision as one of training and equipping Christians in 'whole-of-life discipleship', encouraging leaders to embrace an outwardly focused mission philosophy, and developing programmes to connect with communities across London.

He stressed that London 2013 was about creating a movement of activity across the whole church rather than hosting a one-off event, although an important part of the initiative will be a major public event at which Franklin Graham, the son of Billy Graham, will be preaching.

"Now is the time to call our capital city to an opportunity to hear the Gospel," Mr Gaukroger told the hundreds of leaders present.

"Of course we have our differences, but it is thrilling to know that God wants to work through our unity."

London 2013 organisers are teaming up with the Billy Graham Evangelistic Association to get the capital-wide venture off the ground.

Will Graham, Billy Graham's grandson, was at the launch of London 2013 in Westminster to show his support.

Other leaders at the launch included the Peace Alliance's Nims Obunge, Bishop Michael Nazir-Ali, Andy Frost of Share Jesus International, Global Day of Prayer London convener Jonathan Oloyede and Christianity Explored co-author Rico Tice.
