How should the UK respond to Russian interference threats?

British parliamentary committee said Russia meddled in the 2014 Scottish referendum.

The UK is considering tightening its security laws after an intelligence report on Russian interference. 

A parliamentary committee says no one in government asked about Moscow's attempts to interfere in the 2014 Scottish independence referendum and the Brexit vote two years later.

Prime Minister Boris Johnson has rejected the assessment, while the Kremlin called it "Russophobia".
