M recr fts S licit rs have removed the letter O from our logo on social media as part of National Blood Week.
The official campaign by #missingtype has seen brands all over Britain remove A, O and B from signs and logos to grab attention and urge people to donate in order to maintain supplied of blood.
People are also being asked to join in by taking the letters out of their names and posts on social media and using the hashtag #missingtype.
NHS Blood and Transplant said the number of new volunteers giving blood in England and North Wales has dropped by 40 per cent in a decade.
A spokesperson said the “missing type” campaign raised to raise awareness that if any of the types disappear, supplies may run critically low for patients with cancer, blood disorders, in surgery and with serious injuries.
The NHS said 120,000 fewer people started donating blood in 2014/15 compared to 2004/5.
It needs 204,000 new volunteers this year to ensure nation’s blood sticks continue to remain at a safe level in the future.
