&gt; I would be surprised even in 2030 if India surpasses UK<p>I would be surprised it if didn&#x27;t surpass the UK by then. According to IMF[1], the 2015 GDP of UK and India are 2864 and 2182 Billions USD. All India needs to do is grow about 18% faster than the UK. Assuming UK grows at 3.0% that is 4.8% for India. Hard to see how in the next decade or so of low commodity prices, booming working population, low debt overhang, china slowdown etc., India does worse than that. I would not be surprised if India overtook UK before 2025.<p>[1] <a href="http:&#x2F;&#x2F;www.imf.org&#x2F;external&#x2F;pubs&#x2F;ft&#x2F;weo&#x2F;2015&#x2F;02&#x2F;weodata&#x2F;index.aspx" rel="nofollow">http:&#x2F;&#x2F;www.imf.org&#x2F;external&#x2F;pubs&#x2F;ft&#x2F;weo&#x2F;2015&#x2F;02&#x2F;weodata&#x2F;inde...</a>
