Ladbroke, the betting and hotel group, edged ahead 4p to 242.5p in busy trading as the rumour strengthened it was preparing to intervene in the pounds 180m takeover battle for Capital Corporation, the Crockford's casino business.
The bookies have admitted they are keeping an eye on Capital since London Clubs International barged in with its hostile bid.
The casino tussle has occurred as Ladbroke is pulling in the cash from winding down its property division and is in a comfortable position to mount a counter-strike.
It already owns four London casinos and has made no secret it hopes to expand its gaming presence in London. Capital shares rose 1p to 205.5p and LCI put on 1.5p to 402.5p.
The rest of the market had a lacklustre session weighed down by New York which in turn was fretting about the possibility of higher US interest rates being announced next week.

Yorkshire-Tyne Tees Television was the day's major casualty following Granada's statement it had no current plans to bid. The shares crashed 117.5p to 1,162.5p with the warrants off 122.5p at 957.5p. Granada fell 17p to 956.5p.
The Granada comments came ahead of today's yearly results from United News & Media which has a significant Yorkshire stake and is the biggest holder of the warrants with 34.3 per cent. The warrants, with a 200p exercise price, are running out of time and if United switched it would lift its stake to around 18 per cent.

The securities house, however, put a sell sign over Iceland, the frozen food retailer which is indulging in a share buy-back. The shares melted 4.5p to 95p.
