This is a very short Bill, with just one substantive Clause. As we have already heard, the Bill has a single purpose, which is to enable vacancies among the Lords Spiritual in the House of Lords to be filled as they arise by the most senior female bishop at the time, if there are any appointed at that point, in preference to the most senior male bishop. Male bishops would continue to become Members of the Lords if there were no qualifying female bishops at the time a vacancy arose. The seniority of a bishop is determined under clause 1(3) by reference to the date at which her election as a bishop of a diocese in England was confirmed. This reflects the way in which seniority is determined for the purposes of the Bishoprics Act 1878, which currently provides for bishops to become Members of the House of Lords.

For the avoidance of doubt, I should like briefly to clarify one point. In the Church of England, there are two types of bishop: diocesan bishops and suffragan—essentially assistant—bishops. Future diocesan bishops are often, but not always, given a suffragan appointment first. The Bill relates only to diocesan bishops in England as the Lords Spiritual are drawn only from among their ranks. As the Lords Spiritual are drawn from the diocesan bishops, the Bill will not immediately affect the first female suffragan bishops until and unless they are appointed to a diocese.

While the 1878 Act provides for 21 of the 26 Lords Spiritual to become Members of the House of Lords on the basis of seniority, a further five are automatically Members of the House of Lords on the basis of the see they occupy. These are the holders of the archbishoprics of Canterbury and York and the bishoprics of London, Durham and Winchester. Because the holders of those sees are automatically Members of the House of Lords, clause 1(5) effectively provides for vacancies among those senior ex officio sees to be excluded from these transitional arrangements. When a vacancy arises for one of those five sees, it could be filled by a woman or a man.

Clause 1(1)(a) will ensure that the provisions are time-limited and that they cease to have effect 10 years after the Bill comes into force. The special arrangements must last long enough to provide sufficient opportunities to appoint women as bishops and for female bishops to become Members of the House of Lords as vacancies among the Lords Spiritual arise. Nonetheless, this is rightly a short-term transitional measure that will last until such time as it has become routine for women, like men, to have been in office for several years. The point was made earlier that if representation has not reached the expected level, action could be taken to address that. If the Church is unhappy with the change at the end of the 10-year period, it could ask the Government to take action. I think the Government of the day would respond positively.
