Farmers protesting in Dublin have been urged to stay in the city overnight.

A number of speakers addressed crowds of protesters from the back of a trailer parked on St Stephen's Green this evening.

One of the men told the crowd that there is a "strong plan of action" for tomorrow morning, and said that today's demonstration was the biggest tractor protest ever brought to Dublin. 

More than 100 tractors, along with dozens more vehicles have lined the streets around Merrion Square and St Stephen's Green.

Several road closures in the city centre remain in place and it is understood that organisers plan to remain there until at least tomorrow afternoon. 

The protest began at 2pm, but road closures came into effect on Kildare Street, Molesworth Street, St Stephen's Green and Merrion Square, this morning.

Kevin Street traffic was also affected.

Tractors also made their way to the Merrion Square area, where some protesters attempted to disrupt traffic on a road that was not previously closed by gardaí.

similar protest in November also led to part of the capital being closed off for more than 24 hours.

The organisers of the protest - The Individual Farmers of Ireland - said farmers need a better price for their product to help sustain rural Ireland.

The group has also raised concerns over traceability issues in the food chain.

Earlier, spokesperson Daniel Long said today's demonstration, which was not supported by the main farm organisations, would be "significantly larger" than previous protests.

He said farmers believe the Beef Task Force, which was set up to deal issues in the beef sector, is a "talking shop".
