Shadow Minister for Women and Equalities Gloria De Piero has criticised the appointment of Nicky Morgan as Minister for Women, as she voted against same-sex marriage.

David Cameron’s new Minister for Women, Tory MP Nicky Morgan voted against same-sex marriage by stating “marriage is between a man and a woman.”

In a government reshuffle on Wednesday, sparked by the resignation of Maria Miller, Ms Morgan, MP for Loughborough, was appointed Financial Secretary to the Treasury and Minister for Women.

Speaking to PinkNews, Ms De Piero said as Minister for Women, Nicky Morgan must represent all women, “regardless of sexuality”.

The Shadow Minister for Women and Equalities said: “David Cameron has replaced Maria Miller as Minister for Women with a new Minister who is opposed to equal marriage. As Minister for Women Nicky Morgan must speak for all women and tackle all issues of women’s equality, regardless of sexuality, race or background.”

After voting against same-sex marriage last year, Ms Morgan said: “I totally support civil partnerships and that same-sex relationships are recognised in law. But marriage, to me, is between a man and a woman.”

Mrs Miller, former culture secretary, resigned from government this morning following sustained political and media criticism for over claiming on expenses.

The Basingstoke MP was the minister responsible for steering same-sex marriage through the House of Commons last year.
