The late Johnny Briggs played factory boss Mike Baldwin in the much-loved soap for 30 years.
But his will made no mention of eldest daughter Karen Briggs, who he disowned when she allegedly gave her 14-year-old daughter class A drugs, the Sun has revealed.
His estate was split equally between Jennifer Davies, 43, Michael Briggs, 41, Stephanie Briggs, 39, Anthony Briggs, and Mark Briggs, 58.
