"APJ in particular has form. Three months ago it claimed to be pursuing ‘hundreds' of claims against Liberty in the courts. That approach came to naught so it’s now bombarding the Fos.
"Such vigour says nothing about APJ’s case, which is false. But it speaks volumes about the motivating power of APJ’s fee structure, which charges clients it ensnares fees of over 36 per cent."
In response to Liberty Sipp's claims, a spokeswoman for APJ said the cases issued to the Fos were separate to the court cases it had previously issued against Liberty Sipp, which it said were still ongoing.
She said APJ was committed to ensuring that its clients get the maximum possible compensation "through the most appropriate route for each clients' individual case".
"We operate on a no win, no-fee basis and our fees are in line with legal industry averages for these complex financial mis-selling cases", the spokeswoman added.
