The party claimed that military intelligence was in charge of the alleged plot, while the government dismissed the MDC's claims, saying that Tsvangirai was "playing to the international media gallery." Some observers suggested at this time that Tsvangirai's failure to return called into his question his leadership qualities and made it appear that he was afraid of Mugabe and unwilling to risk coming to harm despite the risks taken by his supporters remaining in Zimbabwe. Tsvangirai returned to Zimbabwe from South Africa on 24 May. He gave what he described as a state of the nation address to the newly elected MDC MPs on 30 May. On this occasion, he said that Zimbabwe was in "a state of despair" and was "an unmitigated embarrassment to the African continent" due to its economic situation, and he also said that those engaging in political violence would receive no amnesty from his government. He also described the MDC as "the new ruling party" and said that the MDC's legislative programme would be "based on the return of fundamental freedoms to the people of Zimbabwe." A new "people-driven constitution" would follow within 18 months, according to Tsvangirai, and a "truth and justice commission" would be established; the army would "defend our borders, not attack our people," while the prisons would "hold only criminals, not innocent people." He pledged that the party would introduce a new strategy combining "demand and supply-side measures" to bring inflation under control. Tsvangirai also promised the revival of agriculture, saying that the issue would be "completely depoliticised" and that there would be measures to "compensate or reintegrate" farmers who lost their land as part of land reform. The government has said that a victory for Tsvangirai would be disastrous and "destabilising." Tsvangirai was detained near Lupane on 4 June, along with his security team and other top MDC officials, such as MDC Vice-President Thokozani Khupe and MDC chairman Lovemore Moyo. A lawyer for the MDC said that Tsvangirai was alleged to have addressed a rally near Lupane without permission. His vehicle was stopped by police at a roadblock and his motorcade was searched; after two hours, he was taken to a police station. The MDC described this as "part of a determined and well-orchestrated effort to derail our campaign programme," while the US government called the incident "deeply disturbing" and the German government demanded his release. Tsvangirai was released later
