The first constituency to report in wasn't "Sunderland"--it was "Sunderland South." Sunderland North has just reported as well, with another Labour victory. Labour now has two districts; the Conservatives and the Lib Dems have none.
Now it's back to Peter Snow, standing in front of a giant virtual swing-o-meter, showing us what will happen if the results from Sunderland (North and South) are typical. Two constituencies isn't a very broad sampling, of course, but the fact that Peter Snow has a giant virtual swing-o-meter makes it seem much more significant.
Something odd: one of the main commentators is American. (I didn't catch his name). It's very odd to hear somebody with the standard American newscaster voice discoursing in such depth on British politics.
