At Conference 2022, the rules on CLP representation was changed and this will impact representation at regional conferences too.
This is Rule, C3.I.1.B which now says, (italics is the new text, strikethrough is deleted,)
Delegates duly appointed by CLPs to the number of one delegate for the first 749 individual members in the constituency or part thereof paying their membership dues as of 31 December in the previous year, and one further delegate for every additional 250 individual members in the constituency or part thereof. No CLP shall be represented by more than 6 delegates in any given year. CLPs must also have paid any outstanding insurance premiums and other levies due before their delegation shall be accepted. To increase the representation of women at Party conference, at least every second delegate from a CLP shall be a woman; where only one delegate is appointed this must be a woman at least in every other year. In a year where a CLP is required to send a female delegate, following a male delegate in the preceding year, but is unable to find one, they will not be entitled to send a man as delegate. In the following year, permission may be granted to send a male delegate if they demonstrate to the conference arrangements committee that they have made every effort to seek a woman delegate.
