More than 50 senior Conservative activists, including chairmen or deputy chairman of the Birmingham Ladywood, Edgbaston and Erdington constituency associations, have written an open letter backing same-sex marriage.
Senior members of the Stourbridge and Halesowen & Rowley Regis constituency associations in the Black Country have also signed the letter.
There has been a lot of publicity about a letter signed by 22 current and former chairman of Conservative constituency associations asking the David Cameron to delay or scrap the proposal.
But senior Conservative activists who back the proposals, to be debated tomorrow evening (Tuesday February 5), have now spoken out.
