Marks & Spencer (MKS) completes the trio of big High Street names reporting this week. Many believe that the recent M&A speculation is the only route the blue blooded retailer can take in order to live up to its fundamental potential, and this speculation reached a peak last month after Arcadia chairman Sir Philip Green raised £500m in a 25% stake sale of his Top Shop and Top Man chain. Although hopes that the cash would add to firepower for a Marks & Spencer bid was subsequently dashed, speculation continues nonetheless.
