April 6 (Reuters) - BP expects to reach its $35 billion net debt target in the first quarter of 2021, the energy group said on Tuesday, following earlier-than-expected proceeds from disposals and a “very strong” quarter. BP said it expects sale proceeds in 2021 to be at the top end of its existing $4 billion to $6 billion range. (Reporting by Yadarisa Shabong in Bengaluru; Editing by Shounak Dasgupta)
