Facts
According to data from the Greater London Authority, 94,001 affordable London homes were built between 2008 and 2016, when Boris Johnson was mayor of London.
63,222 of these were built under the National Affordable Homes Programme - a Labour government scheme over which Boris Johnson had no influence.
Verdict
Another false boast by Boris Johnson about his record as Mayor of London.
We approached Boris Johnson's office, No10 Press Office and the Cabinet Office to give them a chance to comment, but received no response.
