Over a dozen schools are still awaiting exam results which are being held up by the strike at PostNL.

The strike, which began on Monday in Amsterdam and has now spread to other areas of the Netherlands, has hit exam results which were sent to a second school to have the marks confirmed. These results are now stuck in a distribution centre.

It is not known how many pupils are affected.

Freelance delivery workers are protesting at the low tariff being offered by PostNL for each parcel delivered.
