We present an accurate QED calculation of the interelectron interaction corrections for transition probabilities for two-electron multicharged ions. The calculation is performed for the low-lying two-electron configurations (K and L-shells). In particular, the quasidegenerate (1s2p) 21 P1 and (1s2p) 2 3 P1 configurations are under consideration. The total transition probabilities are evaluated. The calculation is performed for ions with the nuclear charge 10≤ Z ≤ 92.
