Sadiq Khan is set to decide whether to give a controversial giant new music venue in east London the green light.
The Mayor is expected to publish his decision on building the huge Vegas-style MSG Sphere in Stratford on November 20.
The Madison Square Garden company began consulting on the 21,500-seater arena dome arena in the capital in 2018.
Plans for the Stratford sphere were approved by the London Legacy Development Corporation (LLDC) last year, despite fierce opposition from some locals.
Levelling Up and Housing Secretary Michael Gove has hinted he wants to further scrutinise the scheme.
In February this year, he issued an Article 31 holding directive, preventing the LLDC and City Hall from signing off the plans before the Government has has time to inspect them.
If Mr Khan rubber stamps the application this month, it will be sent to the Government for final approval.
Members of the London Assembly environment committee warned the ball-shaped venue would produce unacceptable light levels.
A spokeswoman for Mr Khan did not directly respond to the committee’s recommendation, but said the Mayor already asks boroughs to develop their own night-time strategies to address “all aspects of life at night”.
