LONDON, Oct 13 (Reuters) - Britain waded in with 37 billion pounds ($64 billion) of taxpayers' cash to bail out three major banks on Monday, in a move that could make the government their main shareholder.

In return the banks will be forced to curtail the bonuses that many believe encouraged a risk-taking culture that precipitated the global financial crisis. They will also have to scrap dividends.
