Protesters said "this is just the start of the fight" as they marched for a second day in Dover against job cuts at P&O Ferries.

Members of the RMT union and numerous other groups came together after 800 workers were suddenly made redundant over a Zoom call yesterday with no prior warning.

There were chants of "seize the ships" as the group marched down the A20 towards the port, having left the RMT headquarters in Snargate Street at 11am.

The march was led by union bosses and Dover and Deal MP Natalie Elphicke.

Before the group left the RMT offices, speeches were given by Mick Lynch, general secretary of the RMT union, Darren Procter, national secretary, and Labour's former shadow chancellor John McDonnell.

Traffic was held up and delays built after police imposed a rolling block around the march.

Drivers travelling on the opposite carriageway honked their horns in support, while people walking past applauded.

Hundreds of people then set up underneath the White Cliffs of Dover – at the entrance to the Port of Dover – to hear union bosses give speeches.

Ms Elphicke had visited the scene at the RMT building earlier, but was immediately heckled by protesters, who chanted "Shame on you," and "you're on the bosses' side" to which she responded "I stand with the workers".

She told a KentOnline reporter that the move by P&O and its owners, DP World, was a "stab in the back".

"What has happened here is an utter disgrace, P&O Ferries ought to change their mind and DP World ought to back the business as we have backed P&O," she said.

"We are a port town, people have worked for P&O and the other shipping companies for decades, this has been a stab in the back.

"They need to rethink, reinstate these jobs, and support the workers and people of Dover in the same way that we have supported and worked for them for decades."

The RMT is being supported by UNISON, Unite, the Fire Brigade's Union, the Socialist Party and the Hasting and District Trades Council, among others.

Protestors then made their way to Channel House in Dover which is P&O's headquarters, before ending the demonstration at around 2.30pm.

Mr Procter told the crowd that they have ‘scored a huge own goal’ having attracted so much support from the trade unions and the public.

He said the support and backlash is only going to grow and thanked everyone for coming out to support the seafarers today.

He added it won’t be a quick fight, but it will be a ‘fight they are going to win’.

Protesters blocked two roads in the town yesterday for around two hours after news of the job cuts broke that morning.

Earlier, union bosses called for a "militant" response as they sought to rally support for today's protest.
