UK, after banks' rescue, mortgage defaulters

Gordon Brown proposed a governmental plan to rescue mortgage defaulters : a mortgage insurance scheme.
People who are not able to pay their mortgage, because they've lost their jobs or because of a drop of income, could defer their interest payments for up to 2 years.
"The sum forgone by the banks would be added to the mortgage and have to be repaid when the holder's circumstances improved."
If people can't pay their interests after this time, the government would pay the interest deferred.
This plan will concern customers of HBOS, Abey, Natiowide,Lloyds TSB, Northern Rock, Barcklays, Royal Bank of Scotland and HSBC.
Gordon Brown also said that Northern Rock and Bradford and Bingley would delay the repossession, which is "a standard practice anyway".

This plan seems to be a response to people's critics about rescuing plans. People, through government help, were paying the institutions who were the causes of the crisis. Now, people who were " victims of the system" are helped too. This would take a weight away of some customers shoulders, although, if they have more time to pay, they will have more interest to pay too. Opinions seem to be split over this policy : some people don't want to pay, after the banks, for people that "put themselves into debts", and some other are quiet happy with that, such as the Liberal Democrat party, who's saying that he proposed this policy months ago.
But what called my attention is that, as for the nationalisation of a few banks in Great Britain, this policy is state interventionism. According to what I know, the UK wasn't very 'used' to such interventionism. I think that this event, amid other similar ones, shows that a new economic system is slowly coming, or at least that changes in policy are taken. However, I think that in order to manage this change, people's minds and views have to change too, and this is more difficult and long than an economic restructure.
