The first two days in a series of strikes by security staff at London Heathrow have been postponed while workers consider an improved pay offer.

Unite the union said the remaining 29 days of strike action planned for the summer will go ahead if the latest offer is rejected by its members.

The walk-out by more than 2,000 security officers at Terminal Three and Terminal Five was due take place on June 24 and 25.

But Unite said in a statement on Monday: “Following extensive talks with the workers’ union Unite last week, an improved pay offer was made by HAL and, as a gesture of goodwill by the union, the initial strikes were called off.”

Regional Co-ordinating Officer Wayne King added: “Members will now be balloted on the latest offer and they will decide whether or not it meets their expectations.”
