Compact half decent phones under £250

Trying to help someone get their first smartphone, keeping costs down and they want a "shirt pocket"phone?

Pretty tricky I know- I've been looking, and want something that will last them. What is cheap, small but not awful?

Ideally 5.45" screen 18:9 ratio I'd say

@MrSwitch can you work your witchy magic on this one, might be the ultimate challenge
