Blaming the faults of Brexit on remainers wanting to overturn the vote is a funny one. The Tories have had a majority power for the whole time since we’ve left the EU. Every opposing MP could piss and shit all over Westminster as a form of protest and the Tories could still do whatever they wanted in regards to Brexit.
The mass movement of migrants was allegedly solved by Brexit. If it hasn’t been, that’s the fault of the Tories. As a cynic I think having a “migrant crisis” is a net positive for the Tories. They have a scapegoat demographic to target and can look like their busy fixing it whilst doing very little.
