A grandmother who owns the largest collection of royal memorabilia in the world has revealed how her thousands of artefacts are worth more than her £200,000 house.

Self-confessed 'royal nut' Anita Atkinson from County Durham is the proud owner of 7,000 royal items including jugs, tea towels and flags spanning 200 years. 

Items date back to 1760 - with her most prized possession being a framed napkin that was used by Prince Charles during a flight.

Anita's collection is said to be worth more than her house - which is estimated to be worth £203,000.

But the royal historian insists she will never sell the collection as she hopes to pass it down the generations.

Anita has since updated her royal museum - located on an old dairy farm - to include a tribute to Prince Philip.

She had showcased some of the memorabilia built up over the years including portraits, books, coronation tins and jubilee mugs.
