Marks&Spencers?

Is there a marks&spencers branch in malaysia?

Go to marksandspencer.com and do a store search at the bottom of the page. I believe they are only in the UK and Ireland

I want to check why their Return on equity is around 46% but tesco is only at around 20%. I know that this can be because MKS have more debt but I dont know how to find out.

I haven't found any places listing all the ratios or giving breakdown of them. However you can always check the financials. I'll send you an email attachment of them. Check near the bottom, around pg 85 or so.
