Britain’s two major, Conservative and Labour, parties have both been hit by large-scale cyber attacks against their websites just weeks before millions of citizens go to the polls in the country’s national election.

British security services had warned that Russia and other countries could use cyber attacks or divisive political messages on social media to attempt to disrupt the December 12 election.

That attack began shortly before 4pm on Tuesday and lasted for less than an hour without managing to take down any party websites, although it is believed the attacks were unrelated.
