"A snap election resulting – May hopes – in a stronger Tory government and an unambiguous personal mandate is self-evidently the smart option. Such a victory would kill off the idea of a second referendum, and close down the argument that the electorate had not given consent to withdrawal from the single market. This will be a verdict on May, her version of Brexit and her vision for the country."
Hopes to increase Tory majority - to achieve hard Brexit. Of course there are risks, will have to wait and see.
