The tourism minister is meant to promote tourism in and to Britain.
And is nothing to do with passport issuing.

Especially as this was a not prepared speech, but a general comment to those who do not want to go away that there are lots of lovely destinations in UK. The Guardian seems to be making a great deal of of a connexion between events that is not causal. For example "speaking after Theresa May" implies far more than "yesterday"
