April 24 (Reuters) - Embattled French supermarket chain Casino said on Wednesday it would cut between 1,293 and 3,267 jobs as part of its transformation plan aimed at cutting debt and improving its financial situation.

The company, which also aims to sell some of its hypermarkets and supermarkets, added it will aim to focus its business on convenience stores.

Casino, whose restructuring has been undertaken by a consortium led by Czech billionaire Daniel Kretinsky, also announced a 1.2 billion euros ($1.3 billion) investment to modernise its stores by 2028.
