BURNLEY'S final fixture of the season at Charlton could be disrupted by home fans protesting against their owners after supporters promised there would be 'no let-up' in their demonstrations.

A spokesman for protest group the Coalition Against Roland Duchatelet (CARD) insisted the protests will be 'unrelenting' despite the fact that the Clarets are likely to see their battle for promotion go the final day of the season and the trip to the Valley.

A number of the Addicks' recent home games have been delayed by supporters who are protesting against their owner Duchatelet.

On Saturday in their game against Brighton angry Charlton fans released thousands of balloons at kick-off and threw beach balls on to the pitch in the early stages, forcing the game to be halted. It was also briefly stopped in the second half when a smoke bomb landed on the pitch.

It follows similar incidents in home games against Middlesbrough and Birmingham.

Charlton have already been relegated to League One for next season but supporters insist their protests will continue this season, which could provide a major headache to the Football League.

Burnley are currently tied on 87 points at the top of the Championship with Middlesbrough and Brighton, with those two sides set to face each other on the final day of the season.

Serious delays to the game at the Valley could have an impact on all three sides chasing promotion, while some Charlton supporters have also mooted attempts to get the game abandoned, as Blackpool fans did on the final day of last season against Huddersfield at Bloomfield Road.

A spokesman for CARD said in a statement to the South London Press: “The protests will be unrelenting, even if they take different forms to keep the club guessing.

“They will only stop when Duchatelet sells the club.

“We know that Burnley will come to The Valley on the last day of the season in what is set to be an even more critical match for them. We respect that, but the Charlton regime should not imagine there will be any let-up for them, either against Burnley or once the season has finished.

“The campaign has moved up a gear following numerous reports of criticism of the administration by senior players at last Thursday’s kit sponsors’ dinner and open support for protests by former board

members sitting in the directors’ box on Saturday.

“It is telling that while Roland Duchatelet was at The Valley on both Thursday and Friday, he would not stay for the match.

“Given the importance of the match to Brighton’s promotion challenge, their backing for us throughout the day was quite extraordinary and the existing bond between the two sets of fans has been strengthened immeasurably as a result.

“Charlton supporters did themselves proud with what we’ve been told by the Football Supporters’ Federation was one of the biggest protests even seen in the English game.”

The Football Association has also confirmed they have launched an investigation into the protests last Saturday.

"We are investigating this latest matter on the back of previous incidents," an FA spokesman said.

"We had an FA crowd control advisor present at the game at the weekend."
