SESAME Street character Elmo greeted David Cameron as he and his wife Samantha turned up to cast their vote in his Witney constituency.

Bobby Smith, candidate for the party opposing Cameron, the Give Me Back Elmo Party, posed as the children’s TV muppet in a bright red fluffy outfit with his supporters outside the polling station at Spelsbury Memorial Hall in Witney, Oxfordshire.

The Prime Minister gave the Elmo lookalike a brief smile as he emerged from the polling station after 9am, well behind Ed Miliband and Nigel Farage who had both cast their votes earlier.

As the scores of journalists and photographers awaited the result of the tightest race for No.10 in a generation, Cameron entered the station hand-in-hand with his wife Samantha.

The man inside the furry costume started his own party named after his children’s pet, Elmo.

Smith, who claims to have been unfairly treated by the courts and denied proper access to his two young daughters for four years, said: “I’m trying to get David Cameron to address the matter of family law.

“I think it’s too late for me and my girls now because it’s been too long, but I don’t want to sit back and see other people go through it.”

Cameron was also photobombed earlier this week while speaking at a business in north-west London.

As Cameron spoke to the crowd at Utility Warehouse in Hendon, one worker was keen to show his true colours – and they certainly didn’t involve any Tory blue.

As the group appears to listen intently, the man turned around to reveal a Ukip rosette.

Dressed aptly in purple and wearing a knowing smile, the man stared straight into the camera as the PM and his colleagues carried on unaware.
