The Labour leader’s spokesman said he remained wedded to the policy on which the party fought the last general election – and that there was “no reason to expect it is going to change”.
This meant backing “the implementation of the Equality Act, including the single-sex exemption which allows the provision of women-only spaces”.
The stance comes after Labour backbencher Rosie Duffield – who has pulled out of the Labour conference over security fears – protested that she did not know where Sir Keir stood on the issue.
Last week, the Canterbury MP – who has received threats of violence after her comments on transgender rights – questioned whether Labour was about to change course.
She urged Sir Keir to maintain support for “biological females” to fell “protected” in domestic violence refuges, for example, but said she was “not confident” the policy would be upheld.
Ms Duffield held talks with the Labour leader yesterday, as he also met with Labour MPs in the party’s LGBT group.
