To deduct service tax or not from insurance premium?

1. Earlier I had read arguments both in favour of and against of deducting service tax and education cess from life insurance and mediclaim premiums for tax calculation purpose. I would like to know what is the currently accepted view. 2. Suppose someone pays amount(A) as instalment of a term insurance premium, to which is added service tax+ education cess(B) so that total amount paid is C=A+B. The statement mentions that out of this, amount(D) is paid towards critical illness cover (deductible u/s 80D). Unfortunately they do not mention what amount had been paid as service tax and education cess corresponding to critical illness cover premium. What amount of tax deduction should he consider u/s 80C and 80D?
