Former Liberal Democrat MP Lembit Opik described the South Shields result as "appalling" and demanded a "credible explanation from Nick Clegg regarding the recovery strategy".

UKIP's candidate Richard Elvin says coming second is "a message to all three mainstream parties that UKIP is the official opposition".

"It's a message to all three mainstream parties that Ukip is the official opposition.
"We have proved that in Labour strongholds and we have done it again in South Shields."
