Former mayor Boris Johnson is expected to face probing questions today about his role in London’s failed garden bridge project.
The Foreign Secretary is returning to City Hall after he was ordered to appear before a committee of London Assembly members.
The Greater London Authority Oversight Committee issued a summons notice to Mr Johnson after he declined to take part in a review of the project commissioned by current mayor Sadiq Khan.
The investigation, by Labour MP Dame Margaret Hodge, concluded the bridge procurement was flawed.
The £185m bridge linking Temple with Southwark was scrapped in August after Mr Khan refused to sign additional financial guarantees.
An estimated £37m of taxpayers money was lost. Mr Johnson will be questioned for 45 minutes.
