Lord Falconer has confirmed that in the government's view, Price Charles' marriage to Camilla Parker Bowles is legal.

The constitutional affairs secretary released a written statement on Wednesday saying he was satisfied that the wedding did not breach any laws relating to royal marriages.

His comments came as planning for the ceremony continued to attract controversy, with news that the Queen will not attend the wedding event.

The Prince of Wales and heir to the throne is to marry his divorced partner Camilla Parker Bowles in a registry office because, as a divorcee himself, the Church of England would not approve a religious wedding.

Royal Marriages Act

But some experts believe that these and other arrangements, including the fact that Mrs Parker Bowles will not become Princess of Wales or Queen, are inconsistent with the Royal Marriages Act.

Lord Falconer, however, insisted that it is lawful for the couple to marry in a civil ceremony in accordance with the Marriage Act 1949.

Ahead of the statement, Downing Street said Lord Falconer was not reacting to the media furore.

"As we set out at the time of the announcement of the impending wedding, we have to give full advice on issues such as the legality, which we have done," the prime minister's official spokesman said.

"The lord chancellor will set out an explanation of that advice to the House of Lords.

"This is simply an explanation of that advice and all other matters are entirely for the royal household."

Pressed as to whether Tony Blair will personally attend the ceremony he said: "As far as I am aware, no invitation has yet been received and it is normal practice to RSVP before making any public announcement."
