UPDATE 1-Close ends Cenkos deal, says in other bid talks

(Adds details, shares)

LONDON Jan 22 (Reuters) - British investment firm Close Brothers (CBRO.L) said on Tuesday it had ended takeover talks with boutique advisory firm Cenkos Securities Plc (CNKS.L) but remained in discussions with other parties.

Close said it had received an improved 1,025 pence per share bid proposal worth over 1.5 billion pounds ($2.9 billion) from Cenkos and Landsbanki LAIS.IC on Jan. 8, but it was unable to agree a deal, as they required the group to stop investigating a transaction with other parties.

Cenkos, which made an initial approach at 950p per share late last year, said in a separate statement that it no longer intended to make an offer for Close.

Cenkos wanted Close Brothers' corporate finance and asset management units, leaving Landsbanki with the banking division.

Close Brothers, which said in December that it had received further approaches, said on Tuesday its talks with a number of parties remained at an early stage and there could be no certainty they would lead to an offer, "particularly in light of current market volatility".

A source close to the matter had told Reuters that Close was in talks with the private equity firm Blackstone Group about a possible bid at more than 1,000p per share, and had been approached by Indian conglomerate Tata and Japanese financial group Orix (8591.T).

At 1620 GMT, Close Brother shares were down 18 percent at 760 pence, while Cenkos shares were flat, and Landsbanki's down 0.3 percent. (Reporting by Miyoung Kim, editing by Will Waterman)
