Security guards at Heathrow Airport are expected to announce a fresh wave of strikes next week. The strike dates will hit the beginning of the school holidays and the August bank holiday.
The strikes are in relation to a long-running dispute over pay. The dispute has led to workers taking industrial action in the past.
Initially, it was believed that the next bout of strikes would be announced on Friday. It is now believed unions will inform the airport of its intention to strike next week.
