March 21 (Reuters) - Britain’s FTSE 100 jumped to its highest level in five-and-a-half months as its multinational stocks got a boost from weaker sterling, while results-driven slumps in engineering firm Renishaw and trading platform IG dented the midcap index.
The FTSE 100 bounced 0.9 percent, comfortably outperforming its European peers, as the pound dipped amid growing concern that a no-deal Brexit would become a reality.

The Fed on Wednesday abandoned projections for any interest rate hikes this year amid signs of an economic slowdown, and said it would end its balance sheet reduction in September, which softened the dollar.
