The RFU's financial year, which ended 30 June 2003, included the Six Nations triumph and the profit will clear the £19m debt for the development of Twickenham which will see the overall capacity increase from 74,000 to 82,000.
Commented RFU chief executive Francis Baron: "As of today we have £30million net cash in the bank. I am pleased to report another set of good financial results for 2002-03, further strengthening our financial position.
"Following England's victory in Sydney, rugby is enjoying an unprecedented level of exposure from which we can fully exploit the commercial opportunities that will arise in the coming months and years for the benefit of the game of rugby as a whole."
