The UK Government has yet to make a decision on whether it will block controversial gender recognition reforms passed by MSPs last month.
A Downing Street spokesman said the issue was still being looked over fears the Holyrood legislation could impact on the UK-wide Equalities Act.
Tory ministers have until the end of next week to decide whether to issue a Section 35 order - a device used to block devolved laws passed by devolved governments if they cover reserved matters.
The subject could be one of the topics raised when Nicola Sturgeon meets with Rishi Sunak on Thursday evening.
Asked whether the Prime Minister has decided whether to use section 35 of the Scotland Act, which would block Royal Assent, his official spokesman told reporters: “No, there’s no decision made on that."
The official said it was still being looked ahead of a deadline next week. There is a process to consider it and then he will be given advice to make a decision, that’s still taking place."
The spokesman declined to "pre-empt" Sunak’s discussions with the First Minister when asked whether the topic would come up, and said there are “no plans to follow suit” in England.
A spokesman for the First Minister said any attempt to block the GRR bill would be “vigorously contested”.
It comes as another anti-GRR protest was held outside the Scottish Parliament today. Shona Robison, the social justice secretary, has peviously rejected claims from the UK Government that the Gender Recognition Reform (GRR) Bill could negatively impact UK-wide equalities laws.
MSPs from all parties voted to pass the controversial legislation by 86 votes to 39 in December following three days of intense debate and protests outside Holyrood. The passing of the Bill will remove the need for a medical diagnosis of gender dysphoria to obtain a gender recognition certificate (GRC).
It also lowers the minimum age for applicants to 16 and drops the time required for an applicant to live in their acquired gender from two years to three months – six for those aged 16 and 17 – though with a three-month reflection period.
