Irish Times I think. Not my screenshot.
Although, from that article (7 Dec);
AstraZeneca said it was using a continental facility initially because it had booked capacity there “which we wanted to use rather than waste”, not because of problems at the British sites.

I've found the vaccine manufacturer in the Netherlands here (April 2020);
Leiden, The Netherlands (April 15,2020) – HALIX B.V. has joined a consortium of partners under the guidance of the University of Oxford, to provide GMP manufacturing services supporting the large scale production of a COVID-19 vaccine (ChAdOx1 nCoV-19), being developed by the University’s Jenner Institute. This GMP manufacturing scale-up is taking place alongside early phase clinical trials.

On the face of it, I can't see any problem with the UK laying claim to the first batches of the vaccine if HALIX joined the Oxford consortium as early as April 2020.
Further scale up of production here - 8 December;
Leiden, The Netherlands (08.12.2020) – HALIX B.V. signed an agreement with AstraZeneca AB for large-scale commercial drug substance manufacture of AZD1222, the adenovirus vector-based COVID-19 vaccine.
Under the agreement, HALIX will provide commercial manufacturing of drug substance at its state-of-the-art cGMP facility at the Leiden Bio Science Park in the Netherlands. To meet the increased demand, HALIX expands with two additional viral vector production lines.
With this agreement, HALIX continues its key role as one of the original partners in the University of Oxford’s consortium for the manufacture of AZD1222.
