July 1 (Reuters) - Blackstone said on Tuesday it

was considering its options regarding its bid for UK's Warehouse

REIT after its takeover target agreed to a 485.2

million pound ($666.8 million)deal with Tritax Big Box REIT

last week.

The U.S. private equity firm, which had tabled a best and

final offer of 470 million pounds for Warehouse REIT, said the

no increases statement was no longer effective due to the

competing bid.
