Dan, looking at .bzr/branch/branch.conf in that branch we can see "stacked_on_location = /~danbishopuk/lex/trunk" -- it's stacked on the old location for the *same* branch! Did you push this branch up alongside another trunk branch, then rename this new branch to trunk? If so, this is bug #377519.
To fix this, you'll need to remove the stacked_on_location from branch.conf. You can use any SFTP tool (Nautilus or lftp, for example), or the bzr hitchhiker plugin.

Then everything should work again.
