The Sky News presenter was discussing potential rumours surrounding the Prime Minister’s announcement, in which he cited an internet rumour questioning Mrs May’s health.
The Prime Minister eventually emerged from her residence to call a snap general election to be held on June 8, if she is given permission by the House of Commons.
But before she made the monumental speech, Boulton was asked to read out a text message from Fiona Hill, Joint Downing Street Chief of Staff.
Adam Boulton was slammed by Downing Street for speculating on the PM's health

It read: “You might want to tell Bunter that he should watch what he is saying about my boss’s health, utterly unfounded and untrue.
“We will be making a formal complaint to John Riley.”
Quivering under the weight of the threats, Boulton replied: “All I said was there has been speculation about Mrs May’s health, she may want to step down.
“I think we can probably take that as denial from Downing Street, which means if it is not a statement about Mrs May’s health it’s probably more than likely we will have an early general election.”
Addressing the nation, Mrs May said her Cabinet has believed it was the right time for a general election to be called.
