A new member of the team is currently winding everyone up with his demands/requests for updates on other people's work. We're a small team, and he's out to prove himself (or something), and while I'm more than happy to update on my work where appropriate, being asked to let him know where I am with X in a team meeting by a junior member of staff is starting to grate. Manager is useless - seems quite besotted by him. He's not asking out of interest, he seems to be using every opportunity to establish himself as some sort of top dog. It's very weird.
I don't want to come across as negative, and I don't want to let him see he's getting to me - any ideas for a clever comeback and how to deal with him?
