Infighting between Tony Blair and Gordon Brown has put cross-party consensus on pensions reform at risk, the Conservatives have claimed.
Mr Brown and Mr Blair reached a deal on pensions earlier this month
Government proposals include restoring the link between pensions from earnings from about 2012.
Tory spokesman Philip Hammond said Mr Brown had insisted on a "get out clause" which allowed the switch to be delayed after the next election.
But he welcomed most of the plans, aimed at encouraging people to save.
