The Queen's cousin, the Duke of Gloucester, will this week sell more than 800 royal family treasures for up to £2 million - to pay a tax bill.

The auction of the private collection at Christie's in London on Thursday and Friday will raise money to pay his father's death duties.

Among the items up for auction is a Birmingham-made silver inkstand, which was presented to the Duke's late father on the day of his wedding to Lady Alice Montagu Douglas Scott on November 6, 1935, by the Irish Football Association.

It was made by the Adie Brothers and is expected to fetch between £250 and £350.

Visitors to the auction can also bid for another Midlands-produced wedding present belonging to the late Duke and Duchess.

A silver inkwell given to the couple by the villagers of Tid-worth, in Wiltshire, was made by Birmingham silversmith Alexander Clark in 1933 and is expected to sell for up to £200.

The villagers clubbed together to pay for the inkwell during the financial depression of the 1930s.

Money from the sale of a third Birmingham-made wedding present - a £2,000 silver monteith - will be donated to charity by the Duke. It was given to the royal couple by the people of Hawick.

Other items on sale at the auction include a 15th century unpublished treatise on hawks and falcons worth between £80,000 and £120,000, an £80,000 George II mahogany breakfront library bookcase, and a first edition signed copy of Lewis Carroll's Through the Looking Glass.

The book, worth between £10,000 and £15,000, was presented to Alice Liddell who inspired Carroll to write Alice in Wonderland.

A Christie's spokesman said: "This sale is taking place to settle the deferred capital transfer tax liability on the estate of HRH the late Prince Henry, Duke of Gloucester."
