UK grocery price inflation accelerates to 2.5% in the four weeks to October 4th (vs 2.3% in the 4 weeks to Sep), according to Worldpanel

Worldpanel grocery inflation is a private survey of till prices, not the official CPI basket, but it has a track record of feeding into the food component of ONS inflation with a short lag, which is why UK desks treat it as a lead on the sticky services-and-food persistence the Bank of England has flagged. Accelerations from low bases of this kind have tended to matter less for the immediate gilt reaction than for the narrative around the timing of further MPC easing, since food inflation is among the most salient inputs into household inflation expectations, a channel the Bank has repeatedly said it watches. The distinction worth drawing is between cost-push pressure in food, which the MPC has historically been inclined to look through, and broadening domestic price pressure, which it has not; a single grocery print sits in the former camp. The relevant follow-ons are the official CPI food component and any BoE commentary referencing food prices, alongside whether peer surveys point the same way. The tag reads as a misclassification; this is a UK data point.
