London mayor says he will not provide project with guarantees

London mayor Sadiq Khan has effectively pulled the plug on the controversial Garden Bridge, weeks after a scathing report recommended it be scrapped.

Khan today wrote to Lord Mervyn Davies, the chair of the Garden Bridge Trust, informing him that the Greater London Assembly would not provide mayoral guarantees for the project.

The mayor had been assessing a report he commissioned into the Bridge, .

In his letter Khan said the continuation of the project would expose the London taxpayer to additional financial risk, both with regard to the bridge鈥檚 construction and its operation and maintenance.

In a swipe at his predecessor Boris Johnson 鈥 who declined to speak to Hodge as part of her inquiry into the Bridge 鈥 Khan said 鈥渁 considerable amount of London taxpayers鈥 money has already been spent on the Garden Bridge. I have always been clear that not a penny more of taxpayers鈥 money should be allocated to the project.

鈥淗aving assessed all the information available to me including the findings of Dame Margaret Hodge鈥檚 independent review, my view is that providing Mayoral guarantees will expose the London taxpayer to too much additional financial risk.

鈥淲ith planning permission due to expire this year, many outstanding issues remain, including spiralling construction costs and doubts around funding the maintenance of the bridge.

鈥淭he funding gap is now at over 拢70m and it appears unlikely that the Trust will succeed in raising the private funds required for the project. I am simply not prepared to risk a situation where the taxpayer has to step in and contribute significant additional amounts to ensure the project is completed.鈥

The mayor said in his letter that he had been supportive of the Bridge, however the current situation made further backing untenable.

Khan鈥檚 intervention effectively signals the end of the controversial project 鈥 which has been in development for five years 鈥 and the ambitions of Johnson, actor Joanna Lumley and designer Thomas Heatherwick.
