Theresa May has hinted at her football allegiance to AFC Wimbledon. But she may also have some loyalty to the Canaries.

It has been revealed that the prime minister is entitled to use a coat of arms inspired by the famous yellow and green of Norwich's Championship football team.

The revelation came in a College of Arms newsletter - the official heraldic authority of England, Wales and Northern Ireland - which informed readers Mrs May is entitled to bear the Arms of her husband Philip John May.

The Arms, Crest and Badge were created by Mr May's father Robert John May, known as John, in 1997.

The official description reveals the famous yellow and green colours associated with Norwich City Football Club are included in the crest.

Mrs May's husband Philip was born in Norwich in 1957. According to the birth notice in the EDP, he arrived at Drayton Hall - which was a maternity hospital at the time. The May family lived on Taverham Road, later moving to Liverpool.

Following Robert John May's death in 1999, only the prime minister and her husband are allowed to use the coat of arms.

Coats of arms, which date back to the 12th century, belong to specific individuals and families and also corporate bodies as marks of identification.

The motto on the May's shield bears the inscription: 'To thyself be true'. The College of Arms is not allowed to provide a photograph of the May coat of arms, but it provided a description.

The official record describes the coat of arms as 'Per fess vert and or three pallets between four roundels in bend counter changed'. The College of Arms said this meant the shield must divide horizontally in two with three vertical strips up the middle, top to bottom. There should be three pallets between four roundels which should start at the top left and go down to the bottom right. In the top half the stripes or roundels are yellow against green. In the bottom half they are green against the yellow. The tradition dates back to the days which knights taking part in tournaments put coats of arms on their shields. The Earl Marshal, the Duke of Norfolk, has particular powers of supervision over the heralds and the College of Arms.
