【正文】 FPC already have further tools in their armoury. But today we go further.
　　I want to make sure that the Bank of England has all the weapons it needs to guard againstrisks in the housing market.
　　I want to protect those who own homes, protect those who aspire to own a home, and protectthe millions who suffer when boom turns to bust.
　　So today, I am giving the Bank new powers over mortgages including over the size ofmortgage loans as a share of family ines or the value of the house.
　　In other words, if the Bank of England thinks some borrowers are being offered excessiveamounts of debt, they can limit the proportion of high loan to ine mortgages each bankcan lend, or even ban all new lending above a specific loan to ine ratio.
　　And if they really think a dangerous housing bubble is developing, they will be able to imposesimilar caps on loan to value ratios amp。s important that decisions to use these powerful tools are made independently of politics bythe Bank of England.
　　We saw from the last crisis the dangerous temptations for politicians to leave the punch bowlwhere it is and keep the party going on too long. And just in case there is any doubt.
　　I say today, very clearly: the Bank of England should not hesitate to use these new powers ifthey think it necessary to protect financial stability.
　　And I mit that while the Bank and the Treasury will need to design how these powers willwork in detail, and will want to consult on them, I will make sure that they are legislated forand in place before the end of the Parliament.
　　And I also mit today that if the Bank does act in future to limit mortgage lending then thesame rules will be applied to every single Help to Buy mortgage.
　　I know that some would take a more ideological position and end the Help to Buy schemealtogether.
　　They would return to the situation where only those first time buyers lucky enough to have richparents would be able to afford the large deposits demanded by the banks.
　　My approach will be dictated by the facts, not by ideology.
　　And the facts show that Help to Buy is working as intended.
　　As the IMF concluded last week, it is helping lower ine families, overwhelmingly firsttimebuyers outside London, to buy homes priced well below the national average.
　　It is not fuelling house price inflation in London or at the top of the market.
　　It is helping families, and that is how we intend to keep it.
　　So today Iamp。ve already taken big steps to deliver those new homes.
　　Weamp。fought and controversial, like all things worth battling for in politics,and now they are already starting to work.
　　Last week we saw permissions for new homes rising by 20% in a year.
　　Weamp。rsquo。ve got the first garden city for almost a centuryunderway in Ebbsfleet.
　　Now we need to do more. Much more.
　　We have beautiful landscapes, and they too are part of the inheritance of the next preserve them, we must make other promises.
　　If we want to limit development on important green spaces, we have to remove all theobstacles that remain to development on brown field sites.
　　Today we do that with these radical steps.
　　Councils will be required to put local development orders on over 90% of brownfield sites thatare suitable for housing.
　　This urban planning revolution will mean that in effect development on these sites will bepreapproved amp。 while at the same timeprotecting our green spaces.
　　Tomorrow, Boris Johnson and I will jointly set out plans for new housing zones across Londonbacked by new infrastructure, so that we see thousands of new homes for London families.
　　And weamp。rsquo。 and making sure our country couldpay its way in the world.
　　That task is not plete.
　　Our national prosperity is not yet secure.
　　But if we carry on working through our long term economic plan then we can say withconfidence that brighter days lie ahead.
。rsquo。ll take the same approach in the rest of the country。 local authorities will be able to specify the type of housing, not whether thereis housing.
　　And it will mean planning permission for up to 200,000 new homes amp。 and
