The former ‘GM:TV’ and ‘Sky Sunrise’ host bagged the title after a Radio Times poll of more than 33,000 readers.
Eamonn - who is also the nation’s longest serving breakfast host - said in a statement: “I’d like to think that, in some way, you’re not only the longest or just hanging in there but it also equates to being quite good at it.
“If people feel fondly for you, for what you’ve done, or what you’re known as, my goodness me, it begins to make all those early starts, all that lack of sleep, almost worthwhile.”
The results of the poll come after Eamonn previously hailed Piers as the “saviour of breakfast TV”.
Speaking to OK! Online, he said: “Piers Morgan means that there is a breakfast genre to work in. He has saved it…not just for ITV, but for all the other channels as well.
“People have to understand what Piers Morgan brings to the table. You have to be very funny, very controversial, very interesting, very serious, whatever, but you can’t be very boring.
“If you’re bland – which Piers is absolutely not – that’s what makes people watch. So even if they’re watching to slag him off, they’re still watching. That is the brilliant thing.”
Piers joined ‘GMB’ in November 2015, following a successful guest presenting stint earlier that year.
While he has proved to be a divisive figure among viewers, in May it was revealed ratings had increased by 17% over the previous 12 months.
‘Good Morning Britain’ airs weekdays from 6am on ITV.
