( The remnants of) Labour MPs yesterday descended on (fled to) the West Coast for regional "reconnection" visits and a caucus retreat.
Finally, the word retreat is used in it's correct context.
1. the forced withdrawal before an overwhelming force.
2. the act of withdrawing, retirement;
3 .an asylum, as for the insane.
Update: And it seems they can't even retreat without spending 50k of our money.
