LONDON, Nov 9 (Reuters) - Three of London's best-known brokerages have accused Britain's bailed-out banks of "bullying" debt-burdened corporate clients into using their investment banking services, skewing already tough competition.

The chief executives of Panmure Gordon (PMR.L), Numis Securities (NUM.L) and Evolution Securities (EVG.L) said in a joint letter to Paul Myners, Britain's financial services minister, that the behaviour amounted to "corporate bullying".

The letter, seen by Reuters on Monday, does not name part-nationalised Royal Bank of Scotland (RBS.L) and Lloyds (LLOY.L), 43 percent state-owned, but takes aim at both.

"The behaviour of taxpayer-funded banks is stifling competition in the capital markets," the three said, adding independent players who were not bailed out by the taxpayer should not be placed "at a competitive disadvantage".

In the letter sent on Friday, the brokers said the banks should not make it a condition of lending that the company is forced to use the bank's in-house stockbroker.
