Margaret Thatcher: Security tight for funeral

A security operation involving more than 4,000 police officers is under way for the funeral of former UK Prime Minister Baroness Thatcher.

Lady Thatcher's coffin will travel from Westminster and be taken in procession through central London for the funeral at St Paul's Cathedral at 11:00 BST.

Some 2,300 people, representing 170 countries, are expected to attend. The Queen will be among them.

Scotland Yard said it was expecting some protests along the funeral route.

Lady Thatcher, who was Conservative Prime Minister from 1979 until 1990, died on 8 April, following a stroke, at the age of 87.
