The NHS has made an urgent appeal for donors after blood supplies fell by half due to the combination of England's World Cup successes and the recent heatwave.

NHS Blood and Transplant, which manages donations of blood and organs, now urgently needs more donors to come forward in Birmingham to ensure hospital patients get the blood they need.

Nationally, stocks of O negative blood have fallen from the usual six days to just three days' supply and could drop below this in the next few days.

On warm weather days blood donations usually drop by 5% to 10%.

But NHS blood donor centres have seen donations fall further on England’s match days, with a maximum drop of around 20% last Saturday (July 7) when England beat Sweden.

The blood and transplant body have said the sudden drop is due to sunbathing donors being unable to give blood as they have not been able to stay hydrated enough to do so safely. And donors have also watched England's World Cup matches instead of visiting their local blood bank.

The combined effect has cost the NHS in England around 2,000 blood donations in the last two weeks.

Hospital patients in Birmingham urgently need blood every day of the year, whatever the weather.
