Tuesday marks the 200th anniversary of the birth of one of the country's most famous authors, Charles Dickens.

Dickens wrote many famous books including Oliver Twist, Great Expectations and A Christmas Carol.

He was born in Portsmouth in 1812 and died in London in 1850.

On Tuesday Prince Charles and his wife The Duchess of Cornwall will visit the Charles Dickens museum at Doughty Street in London which opened in 1925.

There will be also be a service at Westminster Abbey.

It's being attended by some of the author's descendants including his great-great-grandson, Mark Dickens.

The actor Simon Callow, who plays the role in a stage show in London, says Dickens would have been the most famous person ever in his day - a celebrity as big as any X Factor winner or rock star!
