Earlier today the ONS revealed that house prices had increased by 10.5% in the year to May 2014, up from 9.9% in the year to April 2014, but Brown said there is a limit to what mortgage industry can achieve.

“The MMR has already had a cooling and stabilising effect on lending practices, with borrowers less able to overstretch themselves.”
But he warned that this only highlights a more fundamental problem.
He added: “Families trying to find a home they can afford are not necessarily sticklers for macro-prudential stability.
“At heart we are all facing a very simple problem – there are just not enough places to live to go around.
