Britain will on Tuesday launch a much debated program to help people buy their own homes and set out the small print it hopes will persuade more of the country's big banks to take part.
RBS and Lloyds, both of which are part-owned by the government, have said they will start marketing state-backed "Help to Buy" mortgages this week. Smaller lenders Virgin Money and Aldermore have also agreed to sign up.
But talks with other big lenders have gone down to the wire.
Banks such as Barclays and HSBC want to see how much capital they must set aside to cover loans to home-buyers who may put down deposits of as little as 5 percent. Prime Minister David Cameron and his finance minister George Osborne brought forward the launch of the program to this week from its original start date in January.
They dismiss concerns that the program will fuel a boom-bust cycle in British housing. They say it will help people who have been frozen out of the property market by the big deposits sought by banks which remain wary after the financial crisis.

Critics sas the plan was rushed out to give the government a boost ahead of a 2015 general election, just as former Conservative prime minister Margaret Thatcher reaped the popularity of a program to allow people to buy homes they rented from local authorities in the 1980s.
