My grand niece pushed in the metal dome tweeter of my Tannoy V1i.
Could anyone please help me bring it out again? I know it looks very bad, but I'd rather try the repair. I've tried googling for a replacement but I've found nothing on the web.

Without making any further damage, you have to figure out how to
dismantle the drivers from the box. Either the tweeter is screwed
or pushed in the baffle. You could try to push it out from the inside
when the woofer is out first. Woofer screws are probably under the
decor ring.

Unfortunately once a metal dome tweeter is dimpled, it is very difficult to restore it to its original state. Once disassembled you might succeed to push it back from the inside (use an ear cleaning cotton swab), but it will newer sound like before. The portions damaged (bent, creased) on the dome will produce extra resonances, distortion all over the top octave. If you are not a very "critical ear" you won't hear it anyway, so might worth to give it a try. Pay attention not to deform the voice coil in the process, also the realignment of the coil in the air gap.
Try using a vacuum cleaner and reducing the suction. Has always worked for me. May not get all the creases out but you usually will restore a domes spherical appearance.
The vacuum method doesn not work with metal domes, for sure..... At least not without a level of suction that will rip out the whole dome assembly from its frame.
Sorry my post is misleading, I've used the vacuum method for 'dustcaps' (slaps head). dragonweed maybe right. Dismantling the tweeter as recommended above seems like the best route.
Perhaps you can find some help here:

I've done dome tweeters successfully with a vacuum cleaner. Its all about getting the right diameter tubing to sit snugly on the dome or the dent. A ducted vacuum cleaner was used which has a lot of suction (will lift the carpet if not careful). The other method I've used is a hand solder sucker with adapted tubing. Anything to avoid pulling it apart and the reassembly alignment issues.
Thanks to all who gave advice. I think I will try to decipher how the drivers are installed as in post no. 2. Then as suggested, try to push the dome from behind.
hmmm, seems like I'll be having a hard time opening up the box. There are no screws apparent anywhere.
Did you manage to remove the silver ring on the woofer?
I had once an experience with a cheap sony speaker that
had plastic outer decor basket with screws, only this was all
fake. Had to be pulled up with a tool to get to the real screws
and metal frame. Funny thing.
