I thank my hon. Friend for that. My hon. Friend the Member for Stretford and Urmston (Kate Green) and my noble Friend Baroness Thornton have had many meetings with the British Humanist Association and have worked with the hon. Member for Cambridge (Dr Huppert), who has been a keen supporter of enabling humanist weddings.
I turn to pension survivor benefits, on which a major amendment was passed in the other place. We want to ensure that through this Bill, we make some progress towards addressing the remaining pensions inequalities between same-sex and opposite-sex couples. Measures have already been taken to equalise survivor benefit entitlements for civil partners with those of widowers under public sector and contracted-out schemes, and I welcome that. However, the estimates of the cost of equalising the remaining differences in survivor benefits have so far been very wide ranging. Everyone has accepted that the equalisation of pensions would involve some small and direct cost to private pension schemes, and the Government have asserted at different stages that equalising the benefits for civil partners and married couples of the same sex could result in a wide range of costs, but we have never seen any breakdown of those costs or of how they are calculated.
