Around 1.4 million homeowners could lose a fifth of their disposable income if interest rates are hiked again, a respected think tank has warned.
The Bank of England is expected to raise the base rate - which influences interest rates lenders charge for mortgages, loans and other types of credit - again tomorrow in an effort to curb inflation.
It comes as new figures today show the rate of inflation remained unchanged at 8.7% in the 12 months to May - despite hopes it would fall to 8.4%.
