Miliband heckled as Unions plan 'series of national strikes'
The UK's biggest trade unions have drawn up plans for a sustained campaign of industrial action involving several one-day national strikes, the BBC has learned.
Until now it had been assumed there would be a single day of action in November.
But a senior union leader has confirmed that the action will be more sustained and involve millions of workers.
Labour leader Ed Miliband was heckled at the TUC annual conference for saying that the unions were wrong to strike in June over pensions.
