It's not quite No. 10 Downing Street, but it's close.

The former home of Herbert Henry Asquith - the Prime Minister who took Britain into the First World War - is up for sale in Sutton Courtenay, near Abingdon.

The Grade II listed property, called The Wharf, has seven bedrooms over three floors and is on the market for £850,000 with Oxford estate agent Savills.

Ronnie van der Ploeg, of Savills, said: "The Wharf is a real slice of history, which has changed little since the Prime Minister's days. It saw many famous visitors before and during the war.

"Lloyd George and Winston Churchill both stayed there and Sir Winston is known to have written a letter to his future wife Clemmy from there.

"The house was also a haven for entertainment, with plenty of functions organised there by Prime Minister Asquith's socialite second wife Margot."

In 1930, two years after Mr Asquith died, his widow sold the house to Sir Reginald and Lady Taylor.

It then changed hands several times until 1964, when it was bought by the current owner, Sheila Conder, and her late husband.

Mrs Conder's daughter, Margaret Blacker, who lives with her, said: "Three generations of our family have enjoyed living here but, reluctantly, we have decided the time has finally come for us to move from The Wharf to a smaller house."

She said: "The interior has been preserved largely in its original state, with rough beams and rough cast plaster.

"The walls of the main bathroom, formerly Mrs Asquith's, and separate toilet, are covered in rare pale green and blue glass tiles, similar to those found in Eltham Palace, London.

"A new ensuite shower room was installed in 2005, adjacent to the master bedroom, where Mr Asquith slept."

She added: "Almost every room overlooks the private walled rear garden, which tapers down to an offshoot of the Thames. This was cut to serve a mill and nowadays is monitored by a lock-keeper to ensure the water stays at a safe level."
