The powerful combination of Chandra and XMM-Newton is demonstrating that iron emission lines are common in Seyfert galaxies and is enabling us to separate out narrow from broad components and lowly from highly ionized components. A small but growing population has clear broad lines which are well explained as due to relativistic discs. Many more broad lines may have yet to be recognized due to a combination of low equivalent width, extreme broadness and high inclination. Complex or partial absorption may also mask or mimic broad lines. The lack of broad lines in high luminosity objects needs to be understood. It could be due to a low disc density which leads to the gas being highly photoionized. A clear transition class has not, however, been recognized. MCG-6-30-15 is continuing to display an excellent example of a broad line. The XMM-Newton data indicate that the disc in this object extends well within 6GM/c2 and probably that the black hole is rapidly spinning.
