Removal of an auditor

Hi sir, I just want to check if my understanding of the removal of an auditor is correct.

To remove an auditor,

– The director must forward a ordinary resolution at the general meeting, of which special notice has been given.
– Details of the special notice must be sent to the auditor and the Secretary of State.
– The auditor may then, within the 7 days, submit a statement of circumstance to the company and request that a copy be sent to all the shareholders and have it read out at the general meeting.

– At least 51%(simple majority) of the shareholders must vote in favour to remove the auditor
-Once the auditor is removed, the company may, by passing a special resolution at the same meeting, of not less than 75% of the voting members, appoint another auditor.

Am I correct sir ?
