- A larger Conservative majority could leave May less dependent on backbench hardcore Brexiteers, possibly giving her more flexibility.
- Delaying the following general election until 2022 buys May time for a transitional agreement and a cliff-edge exit becomes less likely.
- The prospect of a Conservative UK government ruling with an increased majority till 2022 will bolster support for Scottish independence.
- The election will delay the start of the Brexit negotiations by one month.
