Lightweight commuter AND Tourer in one?

I'd like a commuter and a tourer but am wondering if there are bikes out there that will adequately fulfill both requirements.

I want a commuter for fast about town riding - lightweight, flat handlebars and disc brakes a must. One of the Boardmans would do fine.

I want a tourer for future trips to Scotland and France so would need the usual robustness and ability to accept panniers.

Any tips or advice?
