Symbiotic stars are interacting binaries with one of the longest orbital
periods. Since they can contain a massive white dwarf with a high accretion
rate they are considered a possible type Ia supernovae (SNe Ia) progenitors.
Among symbiotic binaries there are systems containing a Mira donor, which can
have orbital periods of a few tens of years and more. This subclass of
symbiotic stars due to their very large separation usually was not considered
promising SNe Ia progenitors. We analysed evolution of one of the well studied
symbiotic star with a Mira donor, V407 Cyg. We showed that the standard
evolution model predicts that the system will not become a SN Ia. However, by
simply adding a Wind Roche Lobe Overflow as one of the mass transfer modes we
predict that the white dwarf in V407 Cyg will reach the Chandrasekhar limit in
40-200 Myr.
