Britain's Treasury 'fully supports' work on toughening up gambling rules

Britain's finance ministry said on Tuesday it fully supported a government proposal to toughen up gambling rules, saying reports that it was worried about losing tax revenues were speculative.Shares in bookmakers including William Hill, GVC Holdings and Paddy Power Betfair, fell sharply on Tuesday after newspaper reports said the government would cut the maximum stake on lucrative fixed-odds betting terminals to 2 pounds, the steepest cut under consideration.
