Less than a month before she is due to deliver the budget, Rachel Reeves has admitted breaking rules by failing to apply for a licence from her local council before letting out her south London home.

Keir Starmer accepted an apology from Reeves, who said she had not known a licence was required, and declared the matter closed.
