It’s one of Mumbai’s biggest open spaces, 226 acres of lush turf where horses thunder and thousands take their morning walks. And the city might lose much of that if a grand new plan centred around its elite becomes a reality. The Royal Western India Turf Club (RWITC) has signed a Rs 135-crore ‘‘tourism development’’ deal with Pegasus Clubs and Resorts, paving the way for a golf course at the centre of the Mahalaxmi racecourse. The sprawling ground was leased to the RWITC in 1914. Also on schedule are an exhibition and convention centre, a hotel and a club house — all spread over 6 lakh sq ft. The move has angered many. ‘‘One needs to inquire into the deal. The land outside and inside RWITC is never open for the public. Instead, it’s rented for weddings,’’ says Ashok Batra, a former Navy captain who has started an online ‘‘Save the Racecourse’’ campaign. ‘‘How can such an agreement be given legal sanctity?’’ says Major S.K. Lamba, an RWITC member. ‘‘The area’s development plan clearly shows the green zone reserved as a public recreation ground.’’ Deal Details
