THE number of children affected by the two-child benefit cap will rise by a third over the next five years, an Institute for Fiscal Studies (IFS) report warned today.

The limit currently affects two million children, with more hit each year because it applies to those born after April 5 2017.

Next year, 250,000 more children will be affected, rising to 670,000 before the end of the next parliament, according to the think tank.
