An estate agent’s thankyou letter to Tesco workers has gone viral.

Pregnant Sophie Davison, 24, a branch manager at the Ely branch of haart, collapsed in a Tesco store in Newmarket, Cambridgeshire.

Crucially, staff kept her calm as Sophie, who is six months pregnant, suffered premature contractions.

She went by ambulance to hospital where the contractions were eventually brought under control.

Now back at work after two days in hospital, Sophie posted her heartfelt thanks to the Tesco staff – with over 29,000 people ‘liking’ the post the last time we looked.

Sophie said that in her eyes, the staff had saved her baby’s life by preventing her from panicking.

She said: “They are all heroes. I’ve told them if they have CCTV of it, they can use it for staff training.”
