Since Friday, there’s been some argy-bargy between MPs over which party – the Conservatives or Labour – was responsible for “talking out” an attempt by the shortest-serving Prime Minister in history, Liz Truss, to progress her Private Members’ Bill (PMB) to clarify the meaning of “sex” in the Equality Act 2010, stop the social transitioning of children in schools, and ban healthcare providers from prescribing puberty blockers and cross-sex hormones to anyone under 18 years old.

Truss’s Health & Equality Acts (Amendment) Bill was strongly supported by sex-realist campaign groups such as Sex Matters, but was third on the list of PMBs to be debated on Friday, after the Animal Welfare (Import of Dogs, Cats & Ferrets) Bill introduced by Selaine Saxby, and the Public Procurement (British Goods & Services) Bill introduced by Sarah Champion. And, on what are known as PMB Fridays in the House of Commons, a PMB has to successfully complete its Second Reading by 2:30pm to progress to the next stage of parliamentary scrutiny (Committee stage).

However, after 12 Conservative and nine Labour MPs unnecessarily spent almost four hours debating Saxby’s Bill, despite the Bill already having the enthusiastic support of both the Government and the Labour Opposition, there wasn’t even time to complete the Second Reading of Champion’s Bill by 2:30pm. So Truss’s Bill will now fall to the bottom of the (long) priority list of PMBs to be debated on future PMB Fridays, with zero chance of becoming law.

In truth, Truss’s Bill never had much, if any, chance of becoming law, as last November Truss had come only 18th in the annual ballot that gives MPs the chance to be one of the first 20 MPs to introduce a PMB (out of the more than 400 MPs who entered the ballot), whereas Saxby had come 6th, and Champion had come 12th. Only the top seven MPs in the ballot are guaranteed a full Second Reading debate on their PMB, and without Government support only the top 10-15 PMBs have any realistic chance of becoming law. (Last year, 16 PMBs became law, but many of these were a Government hand-out Bill masquerading as a PMB.)

But that didn’t stop Tory MP Sally-Ann Hart accusing Labour of “talking out” Truss’s Bill, saying Labour has “no interest in safeguarding children against extreme trans ideology”. And it didn’t stop Labour’s Sarah Champion posting a short film on social media in which she accused government ministers of getting Tory MPs to “talk and talk and talk and talk and talk” to prevent her own Bill from progressing. To which Tory MP Jackie Doyle-Price responded: “Come off it, Sarah, you know full well it was your benches going long to prevent any discussion of Liz Truss’s Bill”. And then Sarah Champion hit back with: “Jackie, check Hansard x”.

So, who is right? Well, I checked the Hansard record of Friday’s debates and, as the following chart shows, in the four-hour debate on Selaine Saxby’s Animal Welfare Bill, 12 Tory MPs spoke for a total of 99 minutes (an average of 8m 15s), and nine Labour MPs spoke for a total of 136 minutes (an average of 11m 20s). And, of the 31 (short) interventions, 24 were by a Labour MP, and seven by a Tory MP.

The longest speech (34 minutes) was by Labour shadow minister Steve Reed, while three other Labour MPs – Ashley Dalton, Seema Malhotra and Maria Eagle – collectively spoke for almost an hour. And, as well as making a four-minute speech, Sarah Champion made four interventions, including one in which she used up precious time to tell MPs that her brother once had a ferret called Oscar:

Then, in the (curtailed) debate on Sarah Champion’s Bill that followed, five Labour MPs spoke for a total of 57 minutes (an average of 11m 24s), and one Tory MP spoke for two minutes. Of the seven interventions, four were by a Labour MP, and three by a Tory MP. And, at the conclusion of the debate, one Tory MP made a point of order about Labour MPs ‘talking out’ Truss’s Bill.

So, overall, 13 Tory MPs talked and talked for a total of 101 minutes (that is, 34% of Friday’s debating), while 14 Labour MPs talked and talked and talked and talked for a total of 193 minutes (66% of Friday’s debating). Because the fact of the matter is that, for different reasons, neither the Government nor the Labour Opposition wanted MPs to debate Toxic Truss’s PMB. Government ministers such as Kemi Badenoch want to keep some or all of the measures in Truss’s PMB back as manifesto pledges in the approaching General Election (or for their own Tory leadership campaigns), while Labour shadow ministers are all over the place on the issue and would just like to keep their heads where they’ve had them for the last few years: buried deep in the sand.
