London: Train drivers will next month resume strike action postponed following the death of Queen Elizabeth II, a source told AFP on Friday.

Drivers at 12 train operators will walk out on October 1 and 5, affecting travel to and from the annual party conference of the Conservative party, headed by Britain's new Prime Minister Liz Truss, the source said.

The drivers' union Aslef was not expected to confirm new dates of its industrial action until after the queen's funeral on Monday.

A planned one-day strike by drivers this week was called off.

Tens of thousands of workers across various sectors have gone on strike across Britain since the summer as decades-high inflation erodes earnings.

However, other rail unions and postal workers also postponed strike action after the queen died.

Britain's recent walkouts have been spearheaded by the rail sector, which has carried out its biggest stoppage in more than 30 years.

Some proposed non-rail strikes were halted after unions and companies agreed pay deals at the eleventh hour.

But walkouts have still gone ahead by Amazon warehouse staff and criminal lawyers in recent weeks.

Teachers and health workers have meanwhile hinted at possible walkouts should they not receive new pay deals deemed acceptable.

On Tuesday, it was announced that workers at Britain's largest container port, Felixstowe, will strike for a further eight days.

The walkout from September 27 until early October 5 comes after an initial eight-day summer stoppage at the port in eastern England.
