Data from Public Health England shows the prevalence of variants across all the regions of England, with the Indian variant (light purple) compared to the Kent variant (white/pink). Data shows B.1.617.2 is now dominant in the North West, making up around 70 per cent of all sequenced cases. The proportion of samples analysed in a lab is shown by the black line. The sharp drop off is down to the lag in getting samples analysed and not because of a huge reduction in swabs being checked
