Biden due to announce running mate "imminently", according to reports.

Joe Biden is expected to announce his choice for vice president in the coming days, according to multiple reports. The final decision on the candidate is said to be ‘in his hands alone’, as a screening committee is reported to have disbanded after concluding its work.

‘Rollout plans’ for several candidates are said to have been prepared by Biden’s political team. The campaign believe they could be informed of the presumptive Democratic nominee’s choice as early as today (Tuesday).

While an official announcement today is unlikely, some party staff believe it could be made tomorrow (Wednesday).

Senator Kamala Harris and former US ambassador to the UN Susan Rice are seen as the leading contenders for the VP role.
