UK is a nation where just few years ago several MP's had to either resign or pay back with humiliation after they were not able to justify petty amounts of £4 to usually couple of thousands of pounds. It was nothing much in comparison to bigger scandals and I do not know any MP who was able to retain his seat after the next General Elections.
Now we are talking about a person living in a property worth 42 crores last time I checked on Zoopla.com, having confessed of another property under his name, having found a cash of around 4 crore from his home, Jewellery and bank Accounts and that's a big amount to justify. This is from the person who is not working and is not a registered charity in UK. The cash is a big source of worry for Altaf Hussain but when the pandora box is opened, he is likely to be questioned for each asset his owns under his name (or may have already been questioned).
