Fianna Fáil investigating why website domain Nphet.ie redirects to 'Join Fianna Fáil' page

A search for Nphet.ie takes the user to the Fianna Fáil website.
Fianna Fáil says it is investigating why its party website domain has been linked to people searching for the National Public Health Emergency Team (Nphet).
Internet users who type www.NPHET.ie into their browsers are immediately redirected to the Fianna Fáil party website which advertises: "Join Fianna Fáil."
