Meanwhile bookie William Hill has handed the market some good news.
It said profits for the past year will surpass expectations after it was buoyed by favourable sporting results in December.
The gambling giant said this helped to boost its retail division and increase total group profits.
It said operating profits from continuing operations in 2019 will come in at between £143m and £148m.
Chief executive Ulrik Bengtsson said: "The group has delivered a strong operating performance, ahead of our expectations and against a challenging regulatory backdrop."
Last April, the Government enforced a reduction of the maximum stake for fixed-odds betting terminals from £100 to £2, significantly affecting the revenues of high street betting shops.
