Sir John Manzoni

Sir John Manzoni is a declared insider of Diageo plc, with filings sourced from RNS (LSE). The record holds 31 filings, for trades running from 12 October 2023 to 12 October 2026.

On the market, this insider has only ever bought: 22 purchases, €168k in total. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 9 share grants. So far in 2026, the count stands at 12 purchases and no sales.

Half of the purchases are above €7,597 and half below. Relative to company size, the median is 0.0000% of market cap (9 purchases with a known value). Clusters matter here: 9 out of 21 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

On 12 October 2026 came the latest disclosure, an open-market purchase for €7,764 in Diageo plc. Publication is fast: at least half of the trades appear on RNS (LSE) on the same day. The regulation allows three business days to notify a trade (UK MAR). These figures are compiled from regulatory filings published by RNS (LSE).
