As reported here there have been various statements issued related to "hands only CPR". The American Heart Association have advocated a move to "hands only" CPR dropping the need for nouth to mouth, but the European Resuscitation Council believes there isn't sufficient evidence to warrant a change.

The UK Resuscitation Council have pinned their colours to the mast here, and also believe the evidence isn't compelling enough to require a change before the 2010 congress.

Therefore the current UK and European guidelines can be found here or you can watch a video here.
