The Liberal Democrats' election campaign ground to a halt today when the party's battle bus broke down.
The vehicle was left stranded on the side of the road after it apparently developed an electrical fault on its way back to central London from East Sussex.
Lib Dem leader Nick Clegg was not on the bus at the time, but party officials and journalists were forced to abandon the vehicle in Brixton.
The party's former coalition partners were quick to seize on the incident, with the Conservative press office tweeting:
The technical fault caused the driver's dashboard to light up with warning signs and sparked issues with the electrical systems, according to Press Association reporter David Hughes who was on board at the time.
Attempts to restart the bus have so far failed.
