THE Square Mile is expected to come to a standstill today as workers across the City remember the horrors of September 11.

The New York atrocities were felt deeply in the City, as workers feared for colleagues, friends and loved ones on the other side of the Atlantic.

The London Stock Exchange is stopping for two minutes' silence at 1.46pm, the time the first plane hit, as will the futures and options market Liffe, and most in the City will follow their lead.

Some of the most poignant memorials, however, will be at firms that lost staff in the World Trade Centre.

Investment banking giant Morgan Stanley lost 13 employees and offices around the world will all observe one minute's silence and in New York, a plaque will be unveiled at its new head office dedicated to the late workers.

At City firm Cantor Fitzgerald, it will a particularly difficult day.

About 1,000 people worked on the 101-105th floors of the World Trade Centre's North Tower, and 658 lost their lives in the attacks.

At Lloyd's of London, a solemn and simple ceremony led by the Lloyd's Choir will be held in the Underwriting Room at 10.45am.
