We might never know what was said in the meetings with those Uber officials but I can guarantee that those ministers weren't there to talk about the weather, drain the swamp you might say, well that's easier said than done as everyone in Westminster is probably as bent as a butchers hook, and most of them have been involved in something similar to this so it's probably spoken of as a perk of the job.
One must remember that those MPs are not there to serve their constituents, no, they are there to serve themselves.
