THE Prime Minister's son has set tongues wagging after he was reportedly spotted arm-in-arm with the granddaughter of a wealthy Tory peer from the region.

Rumours of Euan Blair's relationship with Rosie Willoughby, granddaughter of Lord Middleton, who owns a manor house on a 12,500-acre estate in North Yorkshire, have already featured in a Sunday tabloid.

Controversy surrounding their apparent relationship has been heightened because Lord Middleton is chairman of his own Middleton Hunt, which is in stark contrast to the Government's views on hunting.

Miss Willoughby's parents have both denied the rumours, and her father, the Hon Michael Willoughby, has already told reporters that he believes Euan already has a girlfriend at Bristol University, where he is studying.
