The London Stock Exchange bombing occurs at 8:49 a.m. on the morning of July 20, 1990, with the explosion of a 5 to 10 lb. (2.3 to 4.5 kg) bomb of high explosives inside the London Stock Exchange building on Threadneedle Street in the City of London, England, planted by the Provisional Irish Republican Army (IRA). The building and surrounding area are evacuated after the IRA gives a telephone warning 40 minutes prior to the explosion, and thus nobody is wounded. As many as 300 people are evacuated from the building alone. The bomb’s strength blows a 10-foot hole inside the Stock Exchange Tower and causes massive damage to the visitors’ gallery on the first floor, which is frequently used by foreign tourists and schoolchildren and had been scheduled to open ten minutes after the explosion. The bomb is placed in the men’s toilets behind the gallery. The gallery and public viewing area is forced to close in 1992.
The bombing comes on the eighth anniversary of the July 20, 1982, Hyde Park and Regent’s Park bombings which killed eleven soldiers and wounded 53 people. The IRA launches a renewed campaign in London in 1990. During May, a soldier at an army recruiting centre is killed by a bomb in Wembley, while five are injured in a similar explosion in Eltham. In June 1990, bombs at the Honourable Artillery Company (HAC) and the Carlton Club injure 19 and 20 people respectively.
Scotland Yard‘s anti-terrorist chief George Churchill-Coleman says eight phone calls from the same man with an Irish accent are made between 8:02 a.m. and 8:20 a.m. to the City of London Police, the London Fire Brigade, Reuters, the Financial Times, The Salvation Army and the Stock Exchange itself. The caller telephones Reuters just after 8:00 a.m. and says, “This is the IRA. The bomb is due to go off in half an hour at the stock exchange.” The caller then gives a code word that the police say is known to them and used by the IRA to show that its threats are serious, and says, “Clear the building.”
The Stock Exchange’s chairman, however, says after the attack, “If the purpose of this callous act was to bring the City to a halt, they have failed singularly.” The explosion has little impact on stock trading since that is being carried out by computers elsewhere.
A spokesman for Prime Minister Margaret Thatcher says she is “appalled when people leave explosive devices in this manner in public areas.” On October 12, 1984, a bomb planted by the IRA at the Grand Brighton Hotel in Brighton, where the Conservative Party is holding its annual conference, kills five people and comes close to killing Thatcher.
In 1992, the IRA bombs the Baltic Exchange building in the city.
