In recent months, Labour has been setting out detailed plans for how we will act to tackle the cost of living crisis across Britain and in London.
For millions of families in the capital, the costs of buying or renting are the most pressing of all of the mounting demands in that crisis. And for many of those Londoners who used to dream of owning their own home, their hopes are fading as fast as the prices rise beyond their reach.
The cause is simple: there is a chronic shortage of affordable homes in Britain, and nowhere is this clearer than in London.
For a growing number of Londoners, housing costs are the most pressing of all the mounting demands on their wages. These have become the most worrying part of a cost-of-living crisis for more families than ever before.
The Evening Standard's campaigning journalism over recent months has exposed both the scale and some of the root causes of this problem.
It is a problem for young people desperate to find somewhere to live, for families trying to get on the housing ladder, and it is also causing deep difficulty for employers both in the public and private sector. Indeed, the CBI recently highlighted the cost and lack of suitable housing for skilled employees as the biggest threat to London's position as one of the world's greatest cities for business.
The shortage did not begin with this government but, under David Cameron, it is getting much worse. In the past three years, the number of homes built across the country has been lower than at any time since the 1920s. Britain is building less than half the number of houses we need to succeed and prosper. The country deserves so much better.
In London, the Mayor set himself an annual target of 40,000 new homes. Many experts believed that was inadequate. But last year he built only half that number. London deserves better too.
No wonder the average house price in our capital is predicted to rise to an eye watering £600,000 by 2018, while private rents now consume more than half of incomes for many low to middle income families.
There are 180,000 families on the waiting list here for social housing and some of those renting privately are finding themselves in the clutches of some unscrupulous, rogue landlords and letting agents
In these circumstances, it is scandalous that entire blocks of new homes are standing empty, having been marketed and then sold exclusively to investors from abroad on a "buy-to-leave" deal - without Londoners even getting a look-in.Read more
