Washington, Oct 4: Bristol Palin, the 17-year-old daughter of Republican vice presidential candidate Sarah Palin, and her boyfriend are considering a summer wedding.

Bristol’s 18-year-old fiance Levi Johnston’s mother, Sherry, has told Associated Press that the couple is considering next summer for marriage.

"But that could change," Us magazine quoted her, as saying during a short interview outside her home in Wasilla, Alaska.

The baby is due in late December.

It was on September 1 that Palin announced her unwed daughter was pregnant.

In a short statement, the McCain campaign later announced: "Bristol and the young man she will marry are going to realize very quickly the difficulties of raising a child, which is why they will have the love and support of our entire family."

Levi's mother, Sherry, later disclosed that her son, a former high school hockey player, was the father. (ANI)
