PA Theresa May with a blood sugar monitor on her arm to deal with her diabetes
Mrs May uses the device to monitor her blood sugar, which warns her when she has to inject insulin.
The PM rarely shows any outward sign of her medical condition, although in interviews she has always been open about her diagnosis and the way she treats her diabetes.
At last night’s ceremony in Mayfair, Central London, Mrs May joined rivals Jeremy Corbyn and Vince Cable on stage in a striking show of unity.
The trio together paid tribute to PC Keith Palmer, who was killed by a terrorist while protecting Parliament during the Westminster Bridge terror attack in March this year.
