Britain will isolate older people "within weeks" and force into quarantine anyone diagnosed with coronavirus, the government said as it stepped up measures that have so far been less stringent than elsewhere in Europe.

Health Secretary Matt Hancock said people aged over 70 would be shielded from the virus by self-isolating for up to four months, with an announcement "in the coming weeks."

Britain has taken a distinctly different approach to tackling coronavirus from European countries such as Italy, Spain and France which have imposed stringent lockdowns to try to slow the spread of the disease.
