David Cameron joked his blood pressure is going "off the chart" as he makes the final preparations for his keynote speech to the Conservative Party conference tomorrow.
The Prime Minister joked with a nurse as he toured a medical centre in Manchester to highlight a new scheme to extend GP surgery hours.
Chatting with practice sister Julie Lees at the Range Medical Centre, Mr Cameron said he should "set a good example" to the public by having a flu jab but would not "because I've got my speech tomorrow".
"Don't take my blood pressure today either. I think that would probably be off the chart with the worry," he joked.
