At least, that’s the best conclusion I can draw from recent news.
It has been 19 years since the House of Lords Act 1999, which abolished most of the hereditary peers*. Phase 2 of those reforms was due to introduce elected members of the Lords, but despite the Wakeham Report being published in 2000 we are still waiting.
A widely recognised problem with a simple and democratic solution.
But Theresa May wants more time to think about it. 19 years is not long enough for the level of “careful thought” regarding such obvious reform.
Compare this with Brexit. A complicated piece of work, with no obvious solutions to problems like the Good Friday agreement, Gibraltar, Trade. And over which the country is deeply divided.
My best guess is that the thinking time for that will be at least 100 years.
*Fun Fact: Hereditary Peers are the largest group of elected members in the House of Lords, followed by the CofE Bishops and then Liberal Democrats. The caveat is that in every case the electorate is quite small – the remaining hereditary peers elect each other, and the Bishops are elected by various Synods.
