Tomorrow marks one year since the UK went into a national lockdown on March 23, 2020. 

PRIME Minister Boris Johnson first called a national lockdown on March 23 2020, since then we've seen some major milestones in our fight against the coronavirus pandemic. 

Here are some of the key dates and statistics for the 12 months since lockdown began.

All death figures are based on the most up-to-date statistics for people who had Covid-19 recorded on their death certificate, published by the Office for National Statistics.

– March 23 2020: Boris Johnson announces a UK-wide lockdown. The UK’s cumulative Covid-19 death toll, which passed 100 on March 15, now stands at just over 1,000.

– April 2: First of 23 consecutive days when more than 1,000 daily deaths are recorded in the UK.

– April 5: Cumulative death toll passes 10,000.

– April 8: The “deadliest” day of the first wave, with 1,459 deaths occurring in the UK.

– April 17: Cumulative death toll passes 25,000.

– May 22: Cumulative death toll passes 50,000.

– June/July: Most lockdown restrictions are eased or lifted across much of the UK, though new rules – such as face masks in certain settings – are introduced and social distancing continues. Local lockdowns are imposed in some areas where cases start to rise.
