The Government will today announce if it is to cut the maximum stake allowed on fixed-odds betting terminals (FOBTs), described as the "crack cocaine" of gambling.
Currently gamblers can bet up to £100 every 20 seconds on the machines.
A review by the betting regulator the Gambling Commission, published in March, recommended that FOBT slots stakes should be limited to £2, with a stake limit for FOBT non-slot games (which includes roulette) set at or below £30.
Culture Secretary Matt Hancock is widely expected to accept the review's findings, despite opposition from some cabinet colleagues who fear reduced tax revenues and dire warnings of job losses from bookmakers.

And William Hill has warned that new regulations could leave the company at risk of a foreign takeover and
jeopardise 20,000 British jobs.
