Small cracks top of wall just below ceiling

My Brother has bought his first home...paint has started to flake top of wall just below ceiling (ceiling is fine).

Any ideas why and also any suggestions for fixing? Was thinking of scraping loose stuff off then apply PVA, multi/bonding then push Render mesh in and finish with multi blending the plaster in to existing?

Any suggestions appreciated.
