I wrote a personal piece last week about anti-semitism in Britain in the last two years and how it felt to be Jewish. It was repromoted today, on the anniversary of October 7, five days after an attack on a British synagogue in which two Jews were killed.

This is the immediate reply.

Canadian Supreme court. Everyone is dressed in bright red wooly gowns, with a beige trim. It looks sort of like a Santa robe

Tragic news from Canada where the Canadian Supreme Court has gone from the official dress on the left to the one on the right

This was a truly extraordinary day. I am so grateful to all the fellows of @selwyn1882.bsky.social for electing me and to Bishop Sarah for conducting the installation. We all offer her our warmest congratulations on her appointment as Archbishop of Canterbury.

Genuinely this is probably still in force but with Russia as the continuing state (had to do far too much law of state succession earlier in my career) but maybe we’ve therefore suspended it anyway given it’s Russia

I’d start with this one, which sounds like woke nonsense to me. The Royal Navy didn’t build the Empire by worrying about petty things like seaworthiness.

GDPR is a great example of the sort of regulation which (I) creates a bunch of effort for people who want to comply (ii) gets innocently over-zealously deployed (III) becomes deployed as an excuse for orgs not to do things they don't want to and (iv)is fairly easily disregarded by those who want to.

You don’t actually have to both sides this. The Jewish community in the UK is not the Israeli government. You can just condemn the murder of two British Jews killed in their place of worship and you don’t have to say a single other thing.
