I'm sure it won't take long for someone to guess the fault here.

My XM has over the last 7000 or so miles been developing a pull to the right which has become increasingly pronounced. The other weekend I identified and corrected the fault. What was it?

You were wearing a heavy watch on your right wrist?

[White Exec]

Driving around on just three wheels?

[Dieselman]

A tyre with a bias to the right. Other thoughts include a binding front caliper and a wishbone bush worn out.

It's funny, as I was typing it out I had an idea you would get it

The correct answer is a bad tyre; with the tyres swapped front to rear normal service has been resumed. I guess I should really replace it but with plenty tread and no real visible damage it's hard to get my hand in my pocket...

[Dieselman]

Are both front tyres worn evenly across and did you try swapping side to side.
It is possible there is a vehicle fault causing uneven wear, so a pulling develops, but tyres can have bias.

[jonathan_dyane]

Both tyres completely evenly worn so I am fairly confident it is not a fault with the car. It was tyre I bought a part worn which caused the problem...

[jonathan_dyane]

I suspect either a tyre manufacturing fault or some form of damage. Incidentally it also cured a low speed snatch to the drivetrain removing the tyre too so I suspect it is also out of round. I really should replace it.

I bought an XM with a pair of new Goodyear tyres on the front, the steering always pulled to the right until the tyres wore out and I changed them, perfect after that.
