The main candidates in the forthcoming Glasgow North-east by-election have added yet another online dimension to their campaigning efforts, by taking part in an audio interview now available on the website of The Herald newspaper.

The political hopefuls in the by-election have already had the opportunity to take their campaign on to the political blog of The Scotsman group of newspapers and also the website of the Daily Record.

The By-election Special on heraldscotland.com involves the four main candidates and is fronted by political editor, Brian Currie.

It will remain online, on demand, until tomorrow evening.
