Writing an email to “Downing Street All Staff” saying how much he’s enjoyed working with them and that he knows they’re going to keep on doing amazing work, then giving them his personal email address (firstname.lastname@example.org) and saying “keep in touch – and I’m sure I’ll see you in the pub some time!”
