I thought it was April 1st again:

Downing street said she receive a rare ceremonial funeral, with gun carriage, military procession and a service at St Paul's Cathedral, in the style of the funerals of Diana, Princess of Wales and the Queen Mother.Costs are to be borne by the government and Lady Thatcher's estate,

At St Paul's there will be a military guard of honour, and Chelsea pensioners will line the steps. The service will be televised,
