A couple have tucked into a life-sized cake replica of their dog as a birthday treat which has been jokingly described as "psychotic".

Anna Railton and Dr Chris Smowton had a life-size replica of their dog Arthur made in the form of a cake purchased from the Oxford Covered Market.

Ms Railton said: "I think what was ordered was just not a good idea.

"It's a completely psychotic cake.

"They're too good in the Covered Market - too realistic."

The cake was the same size as Arthur, who was barking in the background at the time we spoke to Ms Railton.

The Labour councillor is married to Liberal Democrat Dr Christopher Smowton and both share the same birthday.

When asked whether the differing party allegiances were ever a source of contention, Ms Railton said it was "mostly fine".

She added: "We have a non-aggression pact."
