     Re:  Withdrawal  of Form RW EDGAR Filing Filed on March 15, 2007 and tagged
          with 1933 Act reference: 002-92915

Ladies and Gentlemen:

     Please  withdraw  the MFS  Municipal  Series  Trust Form RW filing that was
filed on March 15, 2007, with accession number 0000912938-07-000226.

     The March 15, 2007 filing incorrectly  referenced the 1933 reference number
002-92915 when in fact it should have referenced File No. 333-141302.

                                        Sincerely,


                                        BRIAN E. LANGENFELD
                                        Brian E. Langenfeld
