The benchmark UK large cap equity index had breached the 7,000 point mark for the first time in its history.
The FTSE 100, which had come close to reaching the mark at the height of the tech boom but had languished since, was pushed through the psychological barrier in a flurry of trading this afternoon.
The UK market was pushed higher after the US equity markets opened up by nearly 1 per cent this afternoon.
Construction company CRH dragged the index higher today, but the highest risers also included mining firms, oil & gas stocks and the UK listing of Coca Cola.
However, not every company has joined in the euphoria, with house builder Persimmon and retailer Next suffering a sell-off.
