English FA set to withdraw support for Fifa president Infantino

But, if not, Uefa will hope it at least helps to secure the 19 votes needed (of 37) to force an emergency meeting of the Fifa Council at which Infantino could face a demand to step down.

That would be triggered if 19 of the 37 Fifa Council members call for one and the meeting must take place within two weeks.

The demand that senior Fifa officials do not destroy any evidence relevant to the scrapped plans to sell off stakes in its competitions will be uncomfortable for those named in the letter, and represents a further escalation in the feud between the two organisations.
