 Those consenting will be randomised to either continue in their current position or be placed in McRoberts position. The woman will be allowed to push for a further 45 minutes. After this time, women in both groups who have not yet delivered will be aided by instrumental delivery, if deemed necessary. A few days after delivery, we will provide women with a questionnaire to determine patient satisfaction and how well they tolerated the procedure they ended up having i.e. Operative delivery or McRoberts position.
