FOLLOWING yesterday’s historic announcement that Prince William is to marry Kate Middleton, the mayor of Welwyn Hatfield has written to the betrothed couple.

Howard Morgan, the civic head of the borough, penned the letter today (Wednesday) on behalf of the area.

The councillor's letter reads:

Dear Prince William and Kate Middleton,

Congratulations on your engagement. On behalf of Welwyn Hatfield Borough Council and the people of Welwyn Hatfield I would like to wish you all the best for the future.

Yours sincerely

Councillor Howard Morgan

The Worshipful Mayor of the Borough of Welwyn Hatfield

The couple announced their engagement yesterday (Tuesday) in front of the world's media.

Prince William avoided questions about whether he got down on one knee, but Miss Middleton said it was very romantic and happened while they were holidaying in Kenya last month.

Miss Middleton was given Princess Diana's engagement ring by William, the pair are set to marry next year.
