60s Sci fi inspired TV help?

[Guy Profumo]

A vague recollection of an "aliens among us" type of thing with a vaguely philanthropic and / or sinister alien, living in London with his girlfriend acting as an observer of humanity, with a view to integration, absorption, takeover, elimination as a threat, whatever
Intervenes to protect people / humanity from similar alien style and occult threats

Anyone remember it / know what it was called?

Nah.

That was American
Where the protagonist "had to get to Washington to prove they existed"


What?

As opposed to the country wide FBI who had the technical skills and technology to pass this on?

All the way to C-in-C of the armed forces?
