West Worcestershire MP Harriett Baldwin plans to bring House of Lords reform back to Parliament this week as she challenges the last bastion of constitutional sexism.

Harriett hopes to resume her campaign to allow the oldest child regardless of sex to inherit hereditary peerages in the House of Lords, by introducing a Private Member’s Bill on Friday.

She won a slot in the ballot to bring legislation forward and pledged to bring back the Hereditary Titles (Female Succession) Bill which ran out of debate time in the last Parliament.

The Bill removes the principle of male-only primogeniture meaning that the 92 hereditary peers occupying one-eighth of the seats in the House of Lords are reserved exclusively for men.

The principle underpinning the bill has been debated in the House of Commons on numerous occasions, including two debates led by Harriett, but the Government still seems wary of supporting the change despite the Crown adopting the same principle by changing the law in 2013.

Harriett commented:

“As a female Member of Parliament, I can't tolerate this constitutional sexism.

“I’m hoping that business in the House of Commons moves smoothly on Friday which will allow me to speak, again, about this important constitutional reform and hopefully allow time for a Minister to respond and support my approach, which I have made narrower in response to some of the objections raised.

“I remain optimistic that this Bill has cross-party support and will spark renewed efforts to end constitutional sexism in the House of Lords.”
