Conner was finally charged with making a seditious speech at Mountmellick in 1841 for which he received a sentence of six months’ imprisonment. As a result of his activities Conner was expelled from the Repeal Association because he proposed that Repealers should not pay rent, county cess, rent charge, tithe poor rate or any other charge arising out of land until repeal was granted. Fintan Lalor agreed with Conner and it was at this stage that his political differences with his Father really began.
