Prudential, which announced last week the merger of its UK asset management arm, M&G, with its European insurance unit, might also consider selling its annuity back-book.
A spokesperson at L&G said that there is no formal process underway for the life company to snap up its rival's pension book.
However, they added: “L&G as made it very clear in its earnings call that they are interested when back-books come to the market."
In a statement on 9 August, during its half-year returns presentation, the company pointed to the reason it may seek to grow by acquisition.
“The combination of Freedom & Choice in Pensions and Solvency II has resulted in consolidation among individual annuity providers.
"We expect there to be further back-book consolidation opportunities over time and we will consider these as and when they arise,” a document disclosed.
Last year, L&G acquired Aegon’s annuity portfolio for £3bn.
This is not the first time that there has been talks about Prudential selling its annuity back-book.
Last year, the insurer hired Clare Bousfield, who orchestrated a £9bn divestment of Aegon's retirement annuities business, and began a search for buyers.
