Transitional State Pension Arrangements for Women

The hon. Gentleman said earlier that the cost would be some £29 billion by 2026. He is completely wrong. The evidence to the Select Committee is that the bill in 2016-17 would be £29 billion and the total cost £77 billion. In Westminster Hall, the hon. Gentleman said that his party would commit to the policy of changing that if it were ever in the unlikely position of having responsibility for running these things itself. Will he confirm that his party leader will say, on the record, that if the SNP ever had responsibility for this, it would commit £77 billion?
