With due reverence Mrs A I was under the impression that it was indeed compulsory for a Parish meeting to be held once a year between the specified dates under the LG act 1972
14(1)The parish meeting of a parish shall assemble annually on some day between 1st March and 1st June, both inclusive, in every year.
(2)Subject to sub-paragraph (1) above and to sub-paragraph (3) below, parish meetings shall be held on such days and at such times as may be fixed by the parish council or, if there is no parish council, by the chairman of the parish meeting." (2014 amended)
Keeping in mind that a Parish Meeting can be called at any time by the community but the annual one must take place- organised, advertised and paid for by the PC
