Abstract: We construct lepton flavour models based on two

A_{4}

modular symmetries. The two

A_{4}

are broken by a bi-triplet field to the diagonal

A_{4}

subgroup, resulting in an effective modular

A_{4}

flavour symmetry with two moduli. We employ these moduli as stabilisers, that preserve distinct residual symmetries, enabling us to obtain Tri-Maximal 2 (TM2) mixing with a minimal field content (without flavons).
