The FTSE committee is to create two new listings of shares to ease pressure on fund managers after Vodafone's £100bn acquisition of Mannesmann, reports The Times.

The committee, which governs the UK's stock market indices, is proposing two shadow indices - one for the FTSE 100 and one for the FTSE All-Share - the larger constituents of which would have their value capped to make up no more than 10% of the market.
