You should be included in all consultation, just like everyone else.
If you are made redundant whilst on maternity leave, you are entitled to the same payout as if you were not - being on ordinary maternity leave does not discount you from those rights. (althought to get statutory payout you must have worked there for two years, otherwise you are note entitled to redundancy payout).
However, if they offer you a job that meets your current skills, and is deemed 'suitable' they can, I think, not give you redundancy pay, as they have offered you an alternative.
There are some rules that someone else will explain better than me, about being offered any job that you are capable of that is suitable if you are in a redundancy 'pool' when on ordinary maternity leave (ie: 26 weeks). This could include fewer (or more) hours as well as less pay, although you could argue that those scenarios where not suitable.
If your position is redundant and there is no suitable alternative you are just as entitled to redundancy pay as if you were not on maternity leave.
You ask if management can ' make' you come in for interview if selection takes place while you are on mat leave. Is it e coming in that bothers you, are you hoping you can insist on a telephone interview or something? Just trying to get what you would prefer.
If you were unsuccessful they would try to redeploy you. When you are on mat leave if your job is made redundant you are entitled to be offered a suitable alternative vacancy where one exists without having to compete, so if it's at all possible to redeploy you they will do so.
The trouble is that if selection for jobs is via interview, there's no getting around that. It's not a question of anyone 'making' you, it's just if you want to be considered you need to be interviewed like anyone else.
Having said that, depending on when the interviews are, you should be able to argue for a postponement or bringing it forward or something if it's very close to your due date or very shortly after the baby being born.
But if it's just that you will find an interview more scary while on mat leave than you would if you were in the office, there's not an awful lot that can be done.
