“...Early indications are that the Conservatives will win a narrow majority...”
What early indications? The final polls pointed to a hung parliament. The first exit poll won’t be released until 10 pm London time (5 pm New York).
Source: Tories confident of overall majority
"A well-placed source within the Conservative campaign machine has told PoliticsHome that early indications are looking good and that he expects an overall Tory majority.
The indications they are receiving are that their voters are turning out, that the advantage in the marginal seats is holding up, and that a number of the lower down Labour target seats will fall their way, making an overall majority likely."
...and probably not a very well-hung parliament at that!
