In the run-up to the Budget, mayor of London Sadiq Khan demanded more power and finance to boost housebuilding and improve infrastructure.
After Philip Hammond’s address to parliament, Mr Khan raged at the “most anti-London Budget in a generation”.
Without the money or control he wanted for ambitious development plans, the question is: what is Mr Khan able to deliver?
Since taking office Labour’s mayor has made little secret of the fact he sees the construction industry as of vital importance to the capital’s economy.
He’s thrown his weight behind many important projects for the sector.
The trouble is much of this support has come in the form of press releases rather than policy decisions.
The mayor’s office would argue that this will change tomorrow when Mr Khan reveals the full details of his “strategic planning bible” or “London Plan”.
In it the mayor will lay out his plans for a major housebuilding spree and significant infrastructure investment in projects like Crossrail 2.
But with limited legislative control, the enactment of many of these policies will come down to soft power coercion rather than hard power law-making.
The effectiveness of Mr Khan will be as much about wooing a room full of foreign investors as it will his passing laws at City Hall.
There is one area where the mayor does have hard power, though: planning.
Mr Khan can push through schemes that have been rejected by local bodies.
The power to push through London’s very biggest construction projects, however, remains at Westminster.
And Mr Khan can only watch as MPs dither on Heathrow’s third runway and debate the merits of Crossrail 2.
It’s all about making the right argument at the right time. And while Mr Khan may not have got the budget he desired, he may still be able to help shepherd through some of the projects that he wants.
