Help required in HSMP form Submission

[LondonGuy]

Hi

I am planning to apply for HSMP while on secondment in UK.
I get full Indian salary in India & tax free living allowance in UK.

I am sending the following docs:

For 3 months in India:

1. Indian Salary slips - signed & stamped
2. Tax return statement of India - cover 9 months
3. Indian Bank Statement – shows clearly the co. name

For 9 months in UK:

1. Indian Salary slips - signed & stamped
2. Tax return statement of India - cover 9 months
3. Indian Bank Statement – shows clearly the co. name
4. UK allowance slips on co. letter head showing the net amount (Not signed & stamped)
5. UK Bank Statement – shows clearly the co. name
6. Deputation letter from the Indian co. which states that I will be getting the full indian salary & allowance in UK(Photocopy)

Can somebody please guide me if the above list of docs is enough for the proof of earning?

What should I write in Cover letter to explain this?

Regards
