A doctor banned from practising in Poland has been able to work in Britain because of a Brexit loophole. William Okanga-Ajwang, 64, was stripped of his right to practise by the Poznan Chamber of Physicians in January 2021. A notification of his loss of licence was circulated by the European Union’s Internal Market Information (IMI) system, which provides details of medical wrongdoing among the bloc’s 27 member states.However, the UK’s General Medical Council did not receive the notification, as the country has been removed from the information-sharing platform. The UK continues to share such information with the EU. Other IMI warnings show another doctor who was struck off in France was able to keep his licence to practise in the UK. However, the recent revelations came after The Times found more than 100 doctors who had been banned from practising in one country had been able to work in the UK.Following the investigation, 11 doctors have been suspended from working and two have been struck off. An investigation last year revealed more than 100 doctors had been working in the UK despite being struck off in another country (stock pic) | GETTY
