Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what requirements Ministers have to declare details of overseas visits in government transparency returns, when meeting external organisations which are not foreign governments, when undertaking official travel overseas.

Ministers' Overseas Travel and Meetings: Publication Guidance, is available on GOV.UK

It states that departments should include official meetings with external organisations held by ministers in the course of visits, including visits overseas (generally visits on their own are not included).

Such guidance has been in place for successive administrations.
