The Clintons will head to New Hampshire on July 13.

WASHINGTON (CNN) — Former President Bill Clinton will visit New Hampshire with his wife Sen. Hillary Clinton on July 13, a Clinton campaign spokesman tells CNN.

The news comes one day after it was learned the former president plans to join his wife, who is seeking the Democratic presidential nomination, on the campaign trail in Iowa next month. It will be the first of many joint appearances, according to the spokesman.

"He will gradually announce more and more of these as his schedule permits," the spokesman said.

According to a recent CNN/WMUR poll, the New York Democrat holds a strong lead over Illinois Sen. Barack Obama in New Hampshire. But A Des Moines Register poll late last month indicates she is not faring as well in Iowa. The poll places the New York Democrat third in the Hawkeye State, behind former North Carolina Sen. John Edwards, and Obama.
