As per a comment from Peter, here's Laura K:
That "at last" is a distinct touch of editorialising.
And it's a firmer version of what she said on the Today programme yesterday morning, where she said, with added 'perhaps' figleaf:
There is some comfort for Theresa may from Michael Gove who is, belatedly perhaps. urging his Brexiteer colleagues to get on board with the deal.
Where you agree with her or not, these really are bursts of opinion. Or, to put it another way, little bias slips.
