Interst on housing loan and repayment

Dear friends

A husband owns a piece of land in his own name.  Husband along with his wife makes an application for housing loan and makes payment of the interest and principal.  The entire amount of the housing loan along with interest is paid out of wife's income.My question is tht whether the wife will be able to claim the interst on the housing loan and the repayment of loan in her income-tax return.  If so how much.

Thanks in advance
