EXHIBIT 1
Letter to the Fund
Transmitted July 10, 2008

Re:	Eaton Vance Insured Florida Plus Municipal Bond Fund ("EIF") and
	Eaton Vance National Municipal Income Trust ("FEV")
	(collectively, the "Funds")

Mr. Pelletier:

We would like to commend the Board for its recently announced recommendation to EIF shareholders to merge EIF into the Eaton Vance Insured Municipal Bond Fund ("EIM") at a special meeting of shareholders to be held in October. Consequently, we wish to withdraw our termination proposal, director nominees and shareholder list request, which were submitted to EIF on April 17, 2008 and April 24, 2008. Given the Board's recently announced action, we also believe that the Board must also address similar circumstances facing shareholders of FEV. In fact, a press release issued by FEV on December 12, 2007 and reiterated again on June 19, 2008 indicated: "... the Board of Trustees of FEV may in the future consider other actions, potentially including a merger of FEV into a similar closed-end Eaton Vance national municipal bond fund." Without further action by the Board, shareholders of FEV continue to bear concentrated geographical risk without any additional benefit for doing so. Thank you for your time and consideration and again I commend the Board for its recently announced solution for shareholders of EIF.

Sincerely,

/s/
Sharon L. Thornton
Senior Director of Investments
