The IPO's success, valuing it at over £5bn, set PartyGaming's market capitalisation higher than the likes of British Airways, Marks & Spencer and hotel group Hilton, putting it on course for a place in the FTSE 100.
BT fell to fourth position as news broke that Ofcom had obliged it to open its network fully to competitors.
The top three slots were filled by supermarkets. Sainsbury's came second on news that sales excluding petrol had beaten its expectations, climbing 1.3 per cent in the 12 weeks to 18 June.
At the other end of the table, The Football Association suffered from Faria Alam's employment tribunal. It fell to second from bottom following reports that Alam emailed friends, family and colleagues about her sexual interest in the association's bosses.
Railtrack plummeted to fifth from bottom after 47,940 former private shareholders of the firm launched a legal battle for £157m in 'fair compensation' against the Government. Railtrack entered administration in 2001 after the Government cut off its subsidy.
