No I think you have got that wrong.
She has to be called a prospective parliamentary candidate until the election is called and Parliament is dissolved and then she becomes a candidate.
You have to get these things right because the law says so: Representation of the People Act 1983, and 1985, as well as the Political Parties Elections and Referendums Act 2000. The Electoral Returning Officer no doubt has people watching these blogspots because we are technically in the "long campaign" part of the General Election.

And dont forget that the above posting by Tatters410 may be have to be declared as an election expense.

Any comments on this all you legal eagles out there?
