Magento: Removing <p> tags from the payment_html variable


When the order mail is sent to the customers, there is a gap in the height in the \“Payment Method\” box (as shown in teh screenshot below)

I inspected the html and found that the variable

 {{var payment_html}} 

is wrapped with a <p> tag.

Can someone please tell me from whre do i remove the


tags from the payment_html variable?

Many thanks
