Deputy prime minister tells Labour conference she expects chancellor to make promise on building at spending review

Angela Rayner has given her strongest hint yet that Labour will announce a major package of social housebuilding in next month’s spending review, warning the party will have abandoned its “moral mission” if it fails to do so.

The deputy prime minister told an event at Labour conference on Sunday she expected Rachel Reeves, the chancellor, to make a promise on social housing next month, with the government under pressure to build hundreds of thousands more social homes.
