How Margaret Thatcher's funeral will play out

LONDON (CNN) -- Prime Minister David Cameron's office has released plans for the funeral of Britain's first woman prime minister, Margaret Thatcher, next Wednesday. Here are the details:

Where: St. Paul's Cathedral in London. The cortege travels the two miles from the Palace of Westminster to St. Paul's through central London, via The Strand.

When: The cathedral doors will open at 9 a.m., and guests are asked to be seated by an hour later. The service is due to start at 11 a.m.

Invitations: More than 2,000 invitations are being sent out. They are color-coded. VIP invitations are white, and those guests will be seated under the cathedral dome. A red or green stripe designates port or starboard.

Other colors denote specific areas of the cathedral.

St. Paul's has a capacity of 2,300 and is expected to be full for the service.

Dress code: Decidedly formal, encompassing "full day ceremonial" without swords; morning dress (black waistcoat and black tie) or a dark suit; and for the women a day dress with hat. Those with medals and honors may wear them.
