Help car wont start

[bodga]

Dropped my mk2 off this morning for an MOT and just had a call saying it cut out when MOT bloke turned headlights on, and now it will not start.


He tells me it turns over but no ign lights on the dash, clock is still on though,


Im thinking alarm or ign switch 

I cannot pick it up till about 5pm but i need some ideas plz

cheers

I was told it passed its MOT though
