As far as I know, the review that was mentioned in the Budget refers to an overall review of the workings of the scheme e.g. qualifying conditions, duration of payment & guidelines for assessment which has been ongoing for some time now, the results of which are to be announced sometime in 2010.
With regard to your particular situation, mortgage interest supplement payments are subject to periodic review by the CWO anyway. This is to ensure that you are actually paying it to your mortgage provider & also to adjust the payment in line with any interest changes that may have affected your loan. You should make sure that you at the very least pay what you have received in your mortgage interest supplement, & perhaps try to make up the difference to the actual interest amount of your loan if at all possible. It is up to you to try to come to some sort of agreement with your lender regarding the repayment of the capital amount.
You should consider approaching your lender to ask them to put you onto an interest only repayment option for a set amount of time pending review, until such a time that your financial situation improves.
