She pulled a face as the children explained their award-winning robot made as part of the First Lego League competition.

One girl described how they created an invention for use in cities to prevent "turtles getting run over and falling down drains" and try to get them back into the sea.

But Mrs May didn't look too impressed as the youngster demonstrated the clever gadget.

She was in Cumbria supporting Tory candidate Trudy Harrison in next week's Copeland by-election.

And she nearly had another photo op clanger as the two women tried to squeeze through a narrow school gate at the same time.

The PM — wearing gold-tipped shoes — managed to skip out of trouble just in time.

The Conservatives hope to nick the Copeland seat from Labour after sitting MP Jamie Reed quit to take a job at the local Sellafield nuclear processing plant.
